Teki Paki

Teki Paki is a falling block puzzle game reminiscent of Puyo Puyo and Tetris, where the players' objective is to compete for the highest possible score by stacking up incoming block pieces that fall from the top of the playfield as a group of three, while avoiding to completely fill the screen with block pieces but failing to do so after they are unable to enter and fill the screen results in a game over, unless players insert more credits into the arcade machine to continue playing.

During gameplay, three square blocks of random colors (red, blue, green, yellow, orange, purple, silver and gold) are dropped and these blocks can be arranged either vertically, horizontally or diagonally to make them disappear after five or more blocks are connected, while more blocks can be added before disappearing. By dropping the block pieces on top of another group placed in the playfield, one of the pieces is unlocked and players can maneuver this sole piece to fill spaces and aim for a chain erase.

When five block pieces are connected, the game enters a new level and each one causes the block pieces to fall faster, with the highest level being 999. There are also two additional special blocks that appear on random occasions; the "Smiley" blocks connects with all the blocks on-screen and the "Bakudan" dynamite that erases all the blocks as well, in addition of granting a 100000-point bonus if players are successful in connecting five of them. The game hosts a number of hidden bonus secrets to be found, which is also crucial for reaching high-scores.
