1 2 3 BOOM!

1 2 3 BOOM! is a pirate slot from Relax Gaming set on open blue water, with a captain, a first mate, a treasure chest, a doubloon, a gun and swords above a flag, a map, a spyglass and a ship's wheel. It plays on five reels and four rows with 1024 ways to win, stakes from 0.1 € to 20 € and a maximum win of 296540 €.

You can choose whether the reels spin side to side or top to bottom; payouts and features stay the same. On each win, the highest win in view pays and explodes, and new symbols fill the gaps. Three or more cannon bonus scatters start a bonus in which every explosive win raises the multiplier, up to 99x, and cannonball wilds can slide in to keep it going. Medium-to-high volatility and a 96.44 % RTP suit players who like chain reactions.

Three or more matching symbols on adjacent reels from the left create a win. The captain is the top symbol at up to 20x the bet for five, and the other premium pirate symbols start at 0.3x. The flag, map, spyglass and wheel pay 0.1x to 1.5x the bet.

• Two spin modes: horizontal or vertical spins with identical payouts and features.
• Explosive wins: the highest win in view is paid, its symbols explode and new ones drop in.
• Cannon bonus: three or more cannon scatters start a feature where each explosive win increases the multiplier, up to 99x; it ends when the cannons are used up and no wins remain.
• Cannonball wilds: slide into view when no win is formed and substitute for all symbols except the cannon scatters.
