Slot Summary

Medieval knights compete as comic performers in Grand Melee, Thunderkick's tournament-themed slot. Its contest takes shape through symbols that stay in place while more join them, with upgrades able to change the value of the assembled group. The humor sits alongside a mechanic concerned with accumulation and transformation.

How It Plays

When the respin feature becomes available, a symbol is selected above the reels. Landing at least five matching instances locks those symbols in their current positions.

The remaining positions then spin again. Further instances of the selected symbol also lock, so a continuing sequence retains its existing matches while adding to the same group.

Features & Win Potential

Symbol Upgrade changes the locked group into a more valuable symbol type. Its effect reaches the accumulated symbols together, making an upgrade relevant to the entire retained group.

Symbol Expansion converts its own position into the selected symbol and fills the reel vertically. Game Area Expansion instead adds another row, creating additional positions for symbols to land.

Bonus & Free Spins

Five or more bonus symbols award free spins, with the number of spins matching the number collected. Bonus symbols can also lock during a respin sequence, allowing that sequence to complete a bonus trigger. The bonus meter resets between spins.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.17%), with wins capped at its top multiplier (5,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
