About
Guide seven geometric pieces into a glowing gravity well. Fill a row to dissolve it, keep the stack low, and use the ghost outline to plan each landing.
Every shuffled bag contains all seven shapes. See three pieces ahead and save one in hold. Clear up to four rows together for bigger scores; every ten cleared rows increases the level and the falling speed.
Tips
- Keep a flat surface and leave room for the long bar.
- Singles score 100, doubles 300, triples 500, and four rows 800, multiplied by your level.
- The ghost shows your landing. Hold a useful shape for later and watch the next three.
- You have half a second to adjust a landed piece, with at most fifteen movement or rotation resets.
