Thunder Coins and Bonus Game
The Thunder Bonus symbol appears only on reel 2. In combination with Bonus symbols, it collects the values of visible coins and jackpots, then adds them to the spin win or the Bonus Game total.
The Bonus Game starts when at least one Bonus symbol appears on each reel. The game then awards 3 respins, resetting to 3 each time a new symbol lands. The Playson guide also specifies the jackpots: Mini 25x, Minor 50x, Major 150x and Grand 1000x.

Game pace
Thunder Coins: Hold and Win remains deliberately compact. The 3x3 grid and 5 lines make reading quick, with tension concentrated on the side Bonus symbols and the central Thunder Bonus. It is a more straightforward layout than a large slot with hundreds of ways.
The potential observed at x5150 gives it more range than a simple fruit game, but the hit frequency of 10.90% and the medium to high volatility mean you should keep your bets cautious.
Point of vigilance
The RTP is not unique. The Playson guide displays four variants, from 95.66% to 90.00%. If you open this game at an operator, you must therefore check the information table of the exact version before playing for real money.
Another point to note: there are no classic free spins in the sources consulted. The action is mainly driven by coin collection, respins, the Pile of Gold and jackpots. For a player looking for a highly narrative slot, the format might seem dry; for a fan of readable Hold and Win, this is rather its strength.
Our quick review
Thunder Coins: Hold and Win works well as a short, clear slot focused on the Thunder Bonus symbol. Its best RTP version remains decent, its x5150 potential gives real depth, but the low RTP variants require you not to play without caution.
