Drift is a calm block puzzle with a gravity twist. Place pieces on an 8×8 board and clear rows or columns to pop them — then tap Drift and everything slides one way, sparking new chain combos. Blocks stay exactly where you drop them, so the board really can fill up. It's a puzzle you can actually lose, played at your own pace. • Zen Mode — unlimited, unhurried, the main way to play • Drift mechanic — shift gravity, clear in chains • Daily Challenge — the same puzzle for everyone, build a streak • 5 calm themes — Midnight, Dawn, Forest, Ocean, Dusk • Fully offline — no account, no data collected, ever • Undo when you need it Drift+ removes ads, unlocks every theme, and gives unlimited undo — or just keep playing free, forever. Sit down, slow down, and drift. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
