Megapanel is a tile-based puzzle game that plays like a mixture of Tetris Attack and a traditional sliding tile puzzle. Blocks rise from the bottom of a well, and the player must slide them around in order to create a row or column of three same-color blocks. This causes the group to clear, and potentially create chains from the blocks above falling. As the game continues, the number of blocks that must be cleared to continue as well as the speed at which the stack rises will both increase.
The game includes three modes. First is training mode which explains the basics of the game. In this mode, a certain number of blocks must be cleared to complete the stage. Second is a "pin-up" mode for one player, where clearing blocks reveals parts of an image of a cute anime girl, the goal being to uncover the entire picture. Last is a two-player Versus (Simultaneous) mode, where players compete to clear their blocks the fastest, and can send garbage blocks to their opponent and fill up their field. The game includes two difficulty settings, two Versus (Simultaneous) modes, a sound test, and a unique mode that displays the entire game in sepia tone
