Joker Boom by KAJOT is a 4-reel, 3-row slot built around an 81 ways to win format. Wins are counted from left to right, and multiple winning combinations can be paid on the same spin. The game uses a fruit-machine theme with symbols including cherries, lemons, grapes, oranges, watermelon, sevens, a Joker Bar wild and a Star scatter.
The Joker Bar wild appears only on the first reel and can replace other symbols, including the Star scatter.

The bonus game is triggered by 3 or 4 Star symbols and awards 10 or 20 boom spins; during this mode, all three positions on the first reel turn into Joker symbols.
