HOW TO PLAY
Fill a course and it goes.
- Slide, turn and drop the seven shapes into the shaft.
- Fill a row across and it settles and clears; four at once pays the most.
- The run ends when a shape has nowhere left to arrive.
It plays by the published rules — seven-bag, SRS wall kicks, hold, ghost and a lock delay you can wiggle in. Three modes: Marathon, Sprint over forty lines, and two-minute Ultra. Each keeps the ten best runs, with the name of whoever set them, and every one of those ten is a replay you can watch.
