sorry about missusing this thread, but i do not want to start a new thread: is there something in the wiki about how drop speed increases in different tetris implementations? for example, i am not sure how to handle starting levels. if one chooses starting level 9, should the speed stay constant for a longer time till it increases to level speed 10, or should it increase the same way as when starting at level 1? what is standard ? how is it handled in different tetris versions?
