Gameplay Mechanics
The Thunder Coins slot runs on 5 reels, 3 rows, 25 fixed paylines. Wins go left to right. The wild covers standard symbols. Coin symbols work separately from payline wins and push toward the Hold and Win trigger. Our specialists checked the Thunder Coins game across different sessions. The base game pays through ordinary combinations at a steady pace. Lightning symbols pay well across multiple positions. Six coin symbols falling together is what the slot is built around.

Special Features
When six coin symbols fall on one spin in Thunder Coins they lock in place and three respins begin. Every coin that falls during those respins also locks and sends the counter back to three, because of which the round keeps running as long as new coins keep falling. Our specialists say that a grand jackpot coin falling near the end of a long round changes the session total more than anything else in the Thunder Coins game. It is precisely because of this that which coin falls matters more than how many lock.
