How Slipgap works

One dot, one input, one shared field per day. Here’s everything that happens under the hood.

1. The control

Hold space, the mouse button, or your finger to make the dot rise; release to let it fall. There is no other control. Timing and rhythm are the whole game.

2. The daily field

Each day has a single deterministic seed that generates one field — identical for every player worldwide. The field always begins solvable and escalates as you progress: the gaps shrink, and later they begin to move. Because everyone faces the same sequence, scores are directly comparable.

3. Server-verified scoring

When you crash, your browser doesn’t send a score — it sends the recorded trace of your inputs. The server replays that trace through the identical deterministic simulation and computes the authoritative score. This is what makes the leaderboard trustworthy: the result is re-derived server-side, not taken on trust from the client.

4. Leaderboard tiers

Today’s leaderboard updates live. Runs that pass verification appear on the verified tier; the design separates verified results from open ones so the top of the board reflects real, re-simulated skill.

5. Ghost racing

A translucent “ghost” — a replay of the rival just above you, or a friend’s run shared via a challenge link — races beside you in lockstep. Because the simulation is deterministic, replaying their trace reproduces exactly where they were at each moment. You can hide the ghost anytime from the toggle above the field.

6. Accounts & cosmetics

Playing is free and needs no account — just pick a nickname. Creating an account (email or Discord) saves your progress, lets you upload an avatar that rides on your dot, and lets you own cosmetic skins. Cosmetics are visual only and never change gameplay.
