No wifi game, no account, no sign up Tap to drop the slab. Land it clean and the run keeps going. Land it short and the overhang is sliced off, so the next one is smaller. It gets harder because your target keeps shrinking, not because it speeds up. Hit the middle and it's a perfect. Chain a few and the slab grows back. That's how you get a real score. The colors shift as you climb, so a run at 10 looks nothing like a run at 80. Every skin and world is earned by playing, 150 to 3,000 crystals. There's a daily gift, and three challenges that change every day. Rewarded ads are always your choice: revive a run, or top up crystals. There's a short ad between some runs, never before your first.
