One direction. Every block.
Choose a direction to shift gravity for the whole board. Blocks slide until something stops them. Matching blocks that touch clear together. Clear the board to reach the next puzzle.
Use the arrow keys, WASD, or the four direction buttons. In a duel, both players get the same puzzles and 120 seconds. Each clear earns 100 points plus 10 for each unused move. Skipping costs up to 50 points. Matching pairs send a gravity pulse: your rival cannot tilt for 1.8 seconds, then gets a five-second shield. Pulses never stack or change their blocks. Resetting cannot farm the same matches. Highest score wins. Practice moves stay on this device unless you choose to save.
Drop Duel is an original gravity puzzle inspired by Gravnic, the alternate mode in the NES version of Puzznic. It uses its own puzzles, art, and code.
