Key Details of the Viking Vanguard Slot

The Viking Vanguard slot is played on a grid of 6 reels and 4 rows with 60 paylines. The minimum bet that you can place is 30p and the maximum is £90. The game uses Flash technology, which may affect how it plays on your mobile device. An I tab is located in the bottom left corner of the screen. You can use this to access the game’s paytable as well as information about how the paylines are structured.

Viking Vanguard Slot RTP

The Viking Vanguard slot has an RTP of 95.90%, which is slightly lower than many other comparable slots. WMS Gaming’s titles often have RTPs around this level. Examples include Beatlejuice Megaways (96.00%), Double Buffalo Spirit (95.96%) and Li’l Red Riches (95.94%).

The Viking Vanguard slot has high variance, so you can expect some thrills and spills along the way as you wait for the big wins to come in. There is an autoplay button, and you can set this to run for a specific number of spins. WMS first released the game at the end of 2014, so it has been on the market for a while now.

How the Viking Vanguard Slot Looks and Sounds

The reels in the Viking Vanguard slot are framed in stone and stand in front of wintry Scandinavian mountain scene. This is pretty detailed, and we were impressed with the quality of the graphics. The game also looks impressive when it comes to the symbols on the reels. There is a level of detail and artistry in them that we have not seen in other WMS games. We particularly appreciated details like the snowflakes that drift across the screen.

The lower value symbols in the Viking Vanguard slot on the reels are Viking runes. They certainly look different from the usual selection of numbers and letters. This certainly is a point of difference between this game and most other slots. There are plenty of higher value symbols populating the reels too. There are 3 metal badges that could be Viking brooches. One of them features a howling wolf as its design, with the other 2 being more figurative in their appearance. You will also see male and female Vikings, a wolf and a raven. The male Viking symbol often appears stacked, taking up 2 spaces on the reel.

Grit your Teeth against the Icy Northern Gales

A dramatic, movie-type musical soundtrack plays. It is embellished with Viking horn flourishes. In addition to the music, you are also treated to various ambient sound effects. These include the howls of the icy Nordic winds, as well as the sounds of tools clinking. This certainly helps to create an immersive atmosphere in the Viking Vanguard slot.

The animation on the reels is very smooth and slick. This is certainly not a game that could be described as clunky or slow. If you like slick slots that call to mind quality arcade games then this is the slot for you. The Viking’s Vanguard slot looks and sounds great.

The Dragon’s Eye Goes Wild for Free Spins

The wild symbol is the dragon’s eye. This appears stacked on 1 of the reels on every spin, something which certainly offers some assistance when it comes to winning. When it forms a win it can turn into an animated dragon too. The scatter symbol is the red Tree of Odin, also known as Yggdrasil. This plays a key role in the game’s bonus features, something that we’ll look at in this section of the Viking Vanguard slot review.

Enjoy a Generous Number of Free Spins in the Viking Vanguard Slot

The Viking Vanguard slot’s only real bonus feature is its free spins. This is not necessarily a bad thing, though. While we always enjoy games that can offer a handful of feature as opposed to just 1, this bonus is very generous. The presence of stacked wilds also adds a certain extra something to proceedings.

Viking Vanguard Snowmobile

The Yggdrasil scatter symbol is what you need to watch for in the Viking Vanguard slot. If 3 or more of this symbol appear on the reels then the free spins are triggered. The number of spins you receive depends on the number of Yggdrasil symbols that appear on the reels. In addition to the free spins, you can also receive a win multiplier if you spin in 4 or 5 scatters. You can see how many spins you receive for each number of scatters below:

  • 3 scatters: 8 free spins
  • 4 scatters: 20 free spins plus a x10 multiplier
  • 5 scatters: 100 free spins plus a x15 multiplier

The feature in the Viking Vanguard slot is made even more generous thanks to the role played by the dragon’s eye wild symbol. During the base game, of course, an entire reel is filled on every spin by this symbol. When the free spins are triggered, the reel on which the wild appeared stacked on the triggering spin will stay wild for the entire duration of the feature.

But this is not the only way that the wild symbol can help. While 1 reel remains entirely wild throughout the free spins, another reel can turn entirely wild at random. This can happen at any point during the free spins, giving you 2 entirely wild reels.

A new reel set is used during the free spins too. This set features a number of adjacent positions that can turn into any symbol except for the bonus. As you can see, this feature does not merely provide you with a really generous number of spins. Its additional multipliers, wild symbols and special reel sets offer you plenty of chances to take home some exceptionally tempting wins. The animation and sound effects also take on a new level of quality during the bonus feature.

Slot Verdict: Thrilling Audio-Visuals

The Viking Vanguard slot is certainly one of the more impressive WMS Gaming titles that we have seen. So we’ll end this Viking Vanguard slot review on a very positive note indeed! This is an excellent game with superb sound and graphics. It also has a very generous free spins feature. This feature can be retriggered and can be extremely lucrative.

If the Viking Vanguard slot has tickled your taste buds into temptation for another Viking slots adventure, then try Vikings Go Berzerk or Age of Asgard from Yggdrasil Gaming. You might also like the iconic slot Thunderstruck from Microgaming.

Viking Vanguard Slot FAQs

How many reels are wild during the free spins in the Viking Vanguard slot?
One aspect of this game we liked was the way that 1 reel turns entirely wild on each spin in the base game. That fun is doubled during the free spins feature, as 2 reels are turned entirely wild. This makes the free spins feature, already generous in terms of the numbers of spins on offer, into something that can be really lucrative. The way that these stacked wilds play such a prominent role is a really positive aspect of this slot.
By far the surest way of picking up wins on the Viking Vanguard slot is to trigger the free spins feature. The male Viking is the most valuable symbol on the reels, paying 150x your stake if 6 appear on a payline. As with all slots, though, it is important to remember that you are at the mercy of the Random Number Generator. The best strategy with slots is to be patient and to manage your bankroll carefully.
How many spins can I collect in the Viking Vanguard slot’s free spins feature?
If you are lucky, you can initially pick up as many as 100 free spins when you trigger the bonus feature in the Viking Vanguard slot. What makes the feature potentially even more generous, however, is that you can retrigger it. This means that you could, in theory, keep picking up 100 free spins over and over again. While possible, this is unlikely to happen, simply because of the law of averages. There is always a chance, though, if you enjoy some really good fortune.

Viking Vanguard

The Viking rocket series of sounding rockets were designed and built by the Glenn L. Martin Company (now Lockheed-Martin) under the direction of the U.S. Naval Research Laboratory (NRL).

Origins[edit]

After World War II, the United States experimented with captured GermanV-2 rockets as part of the Hermes program. Based on these experiments the U.S. decided in 1946 to develop its own large liquid-fueled rocket design, to be called Neptune but changed to Viking. The intent was to provide an independent U.S. capability in rocketry, to continue the Hermes program after the V-2s were expended, and to provide a vehicle better suited to scientific research. The U.S. Navy, in particular, needed a vehicle to study the atmosphere and learn how to predict bad weather which would affect the fleet.

The V-2 would tumble in the rarefied atmosphere at high altitudes. Having been designed as a weapon, the V-2 carried a large payload, approximately one ton of high explosive. This was more than was considered necessary for the scientific instrument payload of a high-altitude research rocket, but in the case of the V-2, used for research, most of the payload was lead ballast required for stable flight,[1]:250 limiting the potential speed and altitude that could be reached with the smaller payloads typically needed for early scientific investigations.

The United States Naval Research Laboratory (NRL), partly at the instigation of the American Rocket Society (ARS), chose to build the advanced sounding rocket. Milton Rosen, head of the Viking project, credits rocket pioneer Robert H. Goddard, the ARS, the California Institute of Technology and the V-2 for the 'profound influence' they had on the design of the rocket.[2]:26 Twelve Viking rockets flew from 1949 to 1955.[2]:28

The Viking was the most advanced large, liquid-fueled rocket being developed in the U.S. at the time.[3]

Design features[edit]

The Viking was roughly half the size, in terms of mass and power, of the V-2. Both were actively guided rockets, fueled with the same propellant (Ethyl alcohol and liquid oxygen), which were fed to a single large pump-fed engine by two turbine-driven pumps. The Reaction MotorsXLR10-RM-2 engine was the largest liquid-fueledrocket engine developed in the United States up to that time, producing 92.5 kN (20,800 lbf) (sea level) and 110.5 kN (24,800 lbf) (vacuum) of thrust. Isp was 179.6 s (1.761 km/s) and 214.5 s (2.104 km/s) respectively, with a mission time of 103 seconds. As was also the case for the V-2, hydrogen peroxide was converted to steam to drive the turbopump that fed fuel and oxidizer into the engine. As its V-2 counterpart, it also was regeneratively cooled.[4][5]

Viking pioneered important innovations over the V-2. One of the most significant for rocketry was the use of a gimbaled thrust chamber which could be swiveled from side to side on two axes for pitch and yaw control, dispensing with the inefficient and somewhat fragile graphite vanes in the engine exhaust used by the V-2. The rotation of the engine on the gimbals was controlled by gyroscopic inertial reference; this type of guidance system was invented by Robert H. Goddard, who had partial success with it before World War II intervened.[2]:66 Roll control was by use of the turbopump exhaust to power reaction control system (RCS) jets on the fins. Compressed gas jets stabilized the vehicle after the main power cutoff. Similar devices are now extensively used in large, steerable rockets and in space vehicles. Another improvement was that initially the alcohol tank, and later the LOX tank also, were built integral with the outer skin, saving weight. The structure was also largely aluminum, as opposed to steel used in the V-2, thus shedding more weight.

Vikings 1 through 7 were slightly longer (about 15 m (49 ft)) than the V-2, but with a straight cylindrical body only 82 centimetres (32 in) in diameter, making the rocket quite slender. They had fairly large fins similar to those on the V-2. Vikings 8 through 14 were built with an enlarged airframe of improved design. The diameter was increased to 114 cm, while the length was reduced to 13 m (43 ft), altering the missile's 'pencil shape'. The fins were made much smaller and triangular. The added diameter meant more fuel and more weight, but the 'mass ratio', of fueled to empty mass, was improved to about 5:1, a record for the time.

Viking Vanguard Legendary Armor

Viking #Launch dateAltitudeRemarks
Viking 13 May 194980 km (50 mi)Prolonged and trying period of ground firing tests. Altitude limited by premature engine cut-off traced to steam leakage from the turbine casing.
Viking 26 September 194951 km (32 mi)Early engine cut-off for same reason as Viking 1. Solved by welding rather than bolting turbine casing halves of subsequent engines.
Viking 39 February 195080 km (50 mi)Suffered from instability in a redesigned guidance system; had to be cut off by ground command when it threatened to fly outside launch range.
Viking 411 May 1950169 km (105 mi)Launched from the deck of the USS Norton Sound near the Equator, almost the maximum possible for the payload flown, in a nearly perfect flight. Guidance system had been reverted to that of Viking 1 and 2.
Viking 521 November 1950174 km (108 mi)Engine thrust was about 5% low, slightly reducing maximum altitude.
Viking 611 December 195064 km (40 mi)Suffered catastrophic failure of the stabilizing fins late in powered flight causing loss of attitude control, which created very large drag and reduced maximum altitude.
Viking 77 August 1951219 km (136 mi)Beat the old V-2 record for a single-stage rocket. Highest and last flight of the original airframe design.
Viking 86 June 19526.4 km (4.0 mi)First rocket of improved airframe design; lost when it broke loose during static testing, flying to just 4 mi (6.4 km) before ground commanded cut-off.
Viking 915 December 1952217 km (135 mi)First successful flight of the improved airframe design.
Viking 107 May 1954219 km (136 mi)Engine exploded on first launch attempt, 30 June 1953. Rocket was rebuilt and flown successfully.
Viking 1124 May 1954254 km (158 mi)Set altitude record for a Western single-stage rocket up to that time.[6]
Viking 124 February 1955232 km (144 mi)Re-entry vehicle test, photography, and atmospheric research.

All except Viking 4 were flown from White Sands Missile Range, New Mexico.

Achievements[edit]

Launch of Viking 4 from the USS Norton Sound at sea, on 11 May 1950

While the underlying motivation for the Viking Project clearly had a national defense component, since it was a U.S. Navy program, it nevertheless established a number of early space exploration landmarks, some technological and some scientific.

Peaceful space travel and space exploration were clearly important objectives that energized many of the higher level instigators even of the German V-2 rocket program, which was funded by the German Army entirely for military purposes. Viking was probably the most ambitious program up to its time, which had significant objectives that were essentially scientific, accompanied by a desire to explore and advance rocket technology for more ambitious peaceful space exploration goals such as artificial earth satellites.[2]:230–235

Technological advances pioneered by Viking included the following:

  • An essentially all-aluminum airframe, with a mass ratio (fueled mass to empty vehicle mass) of about 5:1 for the improved (Viking 8 and later) model. This was a significant improvement over the V-2, which was largely constructed of steel. The altitude records achieved by Viking, for a single-stage rocket, were mostly the result of its light-weight structure.
  • Thrust vector control by gimbaling the rocket motor, as opposed to the graphite vanes used by the German V-2 and the U.S. Army Redstone missiles. This method of control has become standard since, both for reliability and efficiency reasons.
  • Control of the vehicle's orientation, after fuel exhaustion of the main engine, by small auxiliary jets, permitting programmed pointing of scientific instruments, etc.
  • Extensive radio telemetry for both engineering and scientific data, which greatly reduced the number of test flights needed before useful results were obtained.

Among its scientific achievements, firsts up to their time, were:

  • The highest altitude measurement of atmospheric density (by Viking 7).
  • The highest altitude measurement of atmospheric winds (Viking 7).
  • The first measurements of the atmospheric positive ion composition at high altitude (Viking 10).
  • The highest altitude exposures of cosmic-ray emulsions (Vikings 9, 10, and 11).
  • The highest altitude photographs of the Earth (Viking 11).

Through the Viking flights, NRL was first to measure temperature, pressure, density, composition and winds in the upper atmosphere and electron density in the ionosphere, and to record the ultraviolet spectra of the Sun.[2]:234

On 24 May 1954, during a launching from White Sands, New Mexico, a camera mounted in Viking 11 took the first picture of a hurricane and a tropical storm, from altitudes of nearly 160 km (99 mi). The picture embraced an area more than 1,600 km (990 mi) in diameter, including Mexico and the area from Texas to Iowa. This was also the first natural-color picture of Earth from rocket altitudes, clearly showing its curvature.

Viking into Vanguard[edit]

The success NRL achieved in this series of experiments suggest that, with a more powerful engine and the addition of upper stages, the Viking rocket could be made a vehicle capable of launching an Earth satellite. The Viking was thus incorporated as the first stage of NRL's three-stage Project Vanguard vehicle which launched the second U.S. satellite. Two later rockets in the Viking series, Vanguard TV-0 (renamed from Viking 13) and Vanguard TV-1, substantially similar to Vikings 8 through 12, were used as suborbital test vehicles during Project Vanguard, before the first Vanguard vehicle, Vanguard TV-2, became available for test in the fall of 1957.[7] and were designated Vanguard TV-0 and Vanguard TV-1 respectively.
