Coindoku is a fun and challenging wood block puzzle game that combines elements of sudoku and block puzzles. The objective is simple: match blocks of different shapes in lines and 3x3 squares to remove them from the board. But what sets Coindoku apart is that instead of just earning points, you earn coins with each successful match. The more complex the block, the more coins you can earn. It's a game that combines excitement, risk, and logical thinking.

In Coindoku, you can choose a bid to multiply your winning points, with options ranging from doubling your score to increasing it by 20 times. Each multiplier comes with a cost in coins. Once you choose a bid, you can access 3 blocks to place strategically on the board. The goal is to fill up lines and squares to make the blocks disappear and earn more coins. The game features 7 rooms with unique wood designs, combos and streaks for additional rewards, and exciting gameplay that challenges your logic skills.

If you enjoy free puzzle games that test your brain and strategy, Coindoku is definitely worth a try. Whether you want to train your brain or simply relax, this wood block puzzle game offers hours of fun both online and offline.
