Type of play
- Progressive “free games meter” hunting (uncapped/variable-value progressives). You’re buying spins trying to trigger one of four free-games bonuses whose award size (number of free games) has been incrementing.
How the advantage works (what creates +EV)
- Cats Wild Serengeti has four progressive free-games meters: Mini, Minor, Major, Mega.
- Each meter’s free-games count increases when its corresponding bonus symbol lands on reel 4.
- The actual trigger is random (not a must-hit-by). The play becomes +EV only when the current free-games count is high enough that, on average, the expected value of eventually triggering exceeds the expected cost to get there.
