DOSE DOUBLER
A calm, satisfying merge puzzle that's built around one twist nobody else has: you steer every chain. Tap to place, swipe to steer, chain to win.
Now available on the App Store.
Tap-to-place
One-handed, one-thumb play. No tilt, no drag, no fiddly gestures.
Swipe-to-steer chains
When more than one match is possible, you decide where the chain goes.
Daily Challenge
Same seeded run for every player, every day. Streaks. Leaderboard.
10 hand-illustrated tiers
Climb from a humble Tablet to the legendary Panacea.
Three difficulty modes
Easy, Normal, and Hard — flatter spawns and fiercer junk on Hard.
Calm by design
No timers. No energy gates. Drop in, play a run, drop out.
Themes & power-ups
Unlock board themes — Pediatric, OR, Candy Capsule, Space Med Bay, Pet Vet — and lean on Trash and Booster power-ups when a run gets dicey.
