Rise of the Sabertooth

iSoftBet builds Rise of the Sabertooth around a prehistoric cast working through a rocky, bone-littered landscape, styled with a cartoonish, light-hearted tone rather than a serious survival theme. Warpaint-marked animal symbols occupy the reels across a 5x4 grid with 20 fixed paylines, paying left to right when matching symbols land on consecutive reels from the leftmost position.

Card ranks 10 through A form the lower-value symbols, paying 2x to 2.5x the stake for a five-symbol line, while a crocodile, a woolly mammoth, a wolf and the sabertooth tiger itself make up the higher tier, worth 5x to 20x for five matching symbols. A regular wild and a stacked wild both substitute for any paying symbol, with combinations of wilds together paying out at the rate of the highest-value regular symbol rather than stacking on top of it. A mystery symbol also appears, revealing a random paying symbol wherever it lands.

Super Sabertooth Spins trigger whenever a super symbol lands: it expands into a full wild reel, unlocking a multiplier of either x2 or x3 that applies to any resulting win, before the stacked wild shifts one reel to the left and repeats the process. Landing another super symbol during the sequence adds its multiplier to the running total rather than replacing it, and the feature continues until the stacked wild moves off the leftmost reel.

Landing three or four scatters in the base game awards 6 or 8 free spins. During the round, stacked wilds are guaranteed to carry at least an x2 multiplier and trigger extra respins each time they land, continuing until they shift off the reels; these respins don't count against the free spin total, and the round cannot be retriggered. Landing five scatters instead opens a separate Super Free Spins round of 10 spins, where stacked wild multipliers persist for the whole round and add together as new ones land rather than resetting each spin; this round also cannot be retriggered.

A Bonus Buy menu offers two entry points: 6 to 8 free spins for 80x the stake, or the 10-spin Super Free Spins round for 200x the stake.

Volatility is rated medium to high, and the default return to player is 96%. Stakes run from 0.20 up to 20 per spin.
