Chained Fighters Slot by Evoplay

Four gladiator characters serve as the high-paying symbols, and during Free Spins they do more than just pay on lines. After every spin, the Gladiator Clash feature triggers whenever any of them are visible. Each gladiator on the reels enters a fight with a chance to transform into a Locked Wild. Those Wilds stay pinned to their positions for the rest of the Free Spins round - they never disappear.

The accumulation is what drives the math. Early spins might convert one or two gladiators into Locked Wilds, but by spin 8 or 10, significant portions of the grid can be permanently wild. Extra Spins symbols landing during the feature add +2, +4, or +6 more rounds, giving the Gladiator Clash more chances to stack Locked Wilds. The base trigger awards 10, 12, or 15 Free Spins from 3, 4, or 5 Scatters.

In the base game, stacked Wilds appear in groups of 2, 3, or 4 on any reel - the full 4-symbol stack covers an entire column on the 5x4 grid. The Double Chance ante bet raises cost by 1.5x to double the Free Spins trigger rate. Three Buy Bonus tiers go from 66x for 10 spins up to 195x for the full 15. The gladiator arena framing matches the mechanic well - fighters that survive become permanent fixtures on the battlefield.
