Step onto the mysterious stairs guarded by the Fortune Cat and embark on a treasure-hunting journey! When 4 Koban coins or mysterious symbols appear, you enter a bonus-filled secret level. Each level gives you 3 spin chances, and if you land on a new reward symbol, the spin count resets to 3. When the fiery fortune symbol appears, it adds up all the Koban bonus numbers on the board and transforms them into a checkpoint Koban, advancing you to the next level with even higher rewards! If the board is filled with reward symbols, you receive an additional full board bonus of bet x30. The Fortune Cat's lucky paw can randomly add a multiplier, up to x5, and multipliers can stack to easily win more. Are you ready to challenge the levels? Up to 50 levels await you, each accumulating more rewards, helping you to become rich effortlessly!
