123 BOOM!

123 BOOM! by 4ThePlayer is a maritime-themed slot with 5 reels, 1,024 ways to win and medium-high volatility. The game uses a cascading mechanic, where winning symbols are removed and replaced to create further wins on the same spin.

Sliding Cannonball Wilds remove existing symbols from the reels and replace them with new ones, opening space for additional cascades. The game’s bonus BOOM feature applies an increasing multiplier for each explosion, starting at x2 and rising to x99.
