🧱 Stack with leaderboards
A score nobody records is just a moment. Stack plugs into a real ranking economy: ranked duels move an ELO rating, your country's leaderboard shows your flag next to your name, and solo modes keep world boards where a great run outlives your session. Playing well here leaves a paper trail.
How the ranking works
Every quick match adjusts your ELO — the chess system: beating stronger players pays more, losing to weaker ones costs more. Ratings sort into per-country tables (detected automatically, flag included) so you climb your own country before eyeing the world. The full boards live at /rank, and every country's page is in the leaderboards hub.
Climbing with Stack
Since duels shuffle mini-games, your rating reflects range — but sharpening precision under pressure through Stack directly converts to won rounds. The solo modes (Sprint, Tower, Survive and friends) add world-record boards on top, for the days you'd rather fight a number than a person. Leaderboards turn practice into stakes: the same ten minutes trains harder when a rank is watching.
How to play Stack
- A block slides side to side above a fixed base.
- Tap to drop it. One drop — no undo, no second run.
- Your score is the overlap: how much of your block landed on the base.
- Better alignment than your opponent takes the round.
