Description by Sungjun Kim Written by the developer, not by AppBrain. Click to read.
That's the only rule — and now it's a falling-block puzzle.
■ BEAT IT TO BREAK IT
When your piece beats every block it lands on, it smashes them all and keeps drilling down. One tie or loss underneath and it stops right there.
■ CHAIN COMBOS
Every crush in a row multiplies your score: ×2, ×3 and beyond. The landing preview shows exactly how deep you'll drill and which blocks will break.
■ EVOLVE
One button turns your piece into the shape that beats it. You get half a second after touchdown to flip the matchup.
■ CLEAR LINES, SCORE A CTSTRIS!
Fill a row to clear it. Clear four at once for a CTSTRIS! Lines and crushes both push you to the next level.
■ PRESSURE FROM BELOW
Every few pieces, a new row of garbage rises from the bottom. The higher your level, the faster it gets.
• 7 pieces, 3 shapes
• Play with buttons or swipes
• Haptic feedback and punchy crush effects
• Best score tracking
• No ads, no data collected
