Frequently asked questions
Everything you might want to know about Slipgap — the free, daily, one-input survival game.
What is Slipgap?
Slipgap is a free, daily, one-input survival game you play in your browser. Everyone in the world gets the exact same field each day; you steer a single dot through an escalating series of gaps, try to last as long as possible, and compare your run on a global leaderboard.
Is Slipgap free?
Yes — completely free to play, with no install and no paywall. The only optional purchases are cosmetic skins, which are purely visual and never affect gameplay or your score.
Do I need to download or install anything?
No. Slipgap runs entirely in your web browser on desktop and mobile. Open the site and press play — there’s nothing to install.
Do I need an account?
No. You can play instantly as a guest by picking a nickname. Creating a free account (email or Discord) lets you save progress, upload an avatar, and own cosmetic skins.
What does “the same field for everyone” mean?
Each day a single deterministic seed generates one field that is identical for every player worldwide. Because nobody gets an easier or harder layout, the leaderboard is a fair, like-for-like comparison of skill rather than luck.
How is my score calculated?
Your score is how far you survive. When you crash, your browser sends the recorded trace of your inputs — not a score — and the server replays that trace through the identical simulation to compute the authoritative result. The number on the leaderboard is the number the server verified.
Why does the leaderboard have tiers?
Runs that pass server verification appear on the verified tier, kept separate from open results, so the top of the board reflects genuine, re-simulated performance rather than anything a client could simply claim.
What is the “ghost” racing beside me?
The ghost is a translucent replay of a rival’s run — the player just above you, or a friend’s run shared via a challenge link — running in lockstep beside you to pace you. You can hide it anytime with the toggle above the field.
How do I challenge a friend?
After a run, use the “challenge a friend” button to copy a link. When your friend opens it, your run races beside them as a ghost on the same daily field.
What are skins? Do they give an advantage?
Skins change how your dot looks (color, trail, glow). They are purely cosmetic and have zero effect on gameplay, physics, or scoring — they’re just for style.
How do I upload an avatar?
Sign in to an account, then upload an image in the customize panel. Your avatar appears as a small circular “head” on your dot and next to your name on the leaderboard.
Can I play on mobile?
Yes. Slipgap is built for touch — tap and hold to rise, release to fall — and works in any modern mobile browser.
When does the daily field reset?
A fresh field is generated each day at the UTC day boundary, and everyone moves to the new field at the same moment.
How does Slipgap prevent cheating?
The server is the source of truth. It re-simulates every run from the input trace, issues single-use signed run tokens, checks timing and checksums, blocks replays, rate-limits requests, and applies plausibility checks. The browser is never trusted with the score.
