The wild is depicted by the tiger and can substitute for all other symbols to create winning combinations apart from the scatter, however, the tiger wild only ever appears on the 2nd, 3rd and 4th reels and these expand to provide complete wild reels but landing just one wild still rewards players with a single free spin. The scatter is depicted by the Tiger Rush logo symbol, but it will only appear on the 1st and 5th reels and when the player lands two scatters on their reels simultaneously or one scatter with an adjacent wild as in a scatter on the first reel and a wild on reel two the bonus game feature will be activated. Furthermore, players that manage to land these combinations together, will have scatters on the outer reels with adjacent wilds on the 2nd and 4th reels and the reward will be 10 free spins, alternatively landing one or two scatters and one adjacent wild will provide five free spins.
When players enter the bonus game feature the three middle reels expand to provide 25 pay lines and when this happens players will want to keep their eyes peeled for the scatters as landing two will award a further five extra free spins. There are also more free spins awarded as explained above. Finally, in the same way as the wild expands in the base game when landed on the middle three reels, the reels expand providing a potential of three wild reels for every free spin. Whilst Tiger Rush may sound rather complicated it is worth taking advantage of the free version of the slot so that you become au fait with the game mechanics.
Although this is a medium variance slot, there is the potential for players to win up to 1,783 times their stake on each free spin when there are 25 pay lines in play. There is no doubt that this slot is definitely all about the bonus game where there is a total of 20 free spins on offer, and players then play their free spins on the entire 25 pay line reel set. If you are partial to slots that feature a big cat theme I would highly recommend giving Exotic Cats from Microgaming, and if the truth be told Thunderkick do have better slots on offer for example the volatile Pink Elephant slot.
