Don-Chan Puzzle: Hanabi de Don! Advance is a puzzle game developed by Aruze Corp for the Game Boy Advance in 2004. The gameplay is a combination of roulette wheel and Tetris, in which players roll a wheel of colors then place the piece based on the pattern of the wheel. Matching pieces increase the amount of pieces to be dropped on the opponent's side (if there are no pieces to be dropped on the player's side) or decrease the amount of pieces on the player's side (if there are any pieces on their side). The player can match 7s in a row for a chance to launch fireworks and increase the amount of pieces on the opponent's side.
NoMercy defeats all opponents on the easiest difficulty as fast as possible.
