Rotation system is a right-handed Nintendo Rotation System. Lock delay, wall kick and hard drops were not implemented. Softdrops were allowed, and the players were rewarded 1 point per cell (Max of 20). DAS initial delay is 16 frames, and then every 6 frames. Soft drop speed is 1/2G. ARE is 10~18 frames depending on the height at which the piece locked; pieces that lock in the bottom two rows are followed by 10 frames of entry delay, and each group of 4 rows above that has an entry delay 2 frames longer than the last; line clear delay is an additional 17~20 frames depending on the frame that the piece locks; the animation has 5 steps that advance when the global frame counter modulo 4 equals 0. As a consequence, the first step of the line clear animation is not always a set number of frames
