About Runner Gacha
A free browser-based endless runner with a collectible skin system, built as an independent project and playable without an account, an install or a payment.

What the game is
Runner Gacha is a one-button endless runner. You control a block that accelerates to the right; you jump obstacles, collect coins, and spend those coins on a gacha wheel that unlocks skins for your player, the background and the obstacles you jump over.
It runs entirely in the browser on an HTML5 canvas. There is no download, no launcher and no store account — the game is a single page that loads in a couple of seconds on a phone connection, which was a deliberate constraint from the start.
Why we built it
Most browser games either ask you to install something, gate the interesting content behind a paywall, or hide their random-reward odds. Runner Gacha was built to test whether a collection-driven game could work without any of those: free, instantly playable, and honest about its numbers.
That is why the drop rates and the pity threshold are published in full rather than buried. If a game is going to ask you to spin a wheel, you should be able to see what the wheel is doing.
How it is made
Rendering
Vanilla JavaScript on an HTML5 canvas — no game engine and no framework. That keeps the whole game to a single page load.
Audio
Web Audio API for effects, with separate music and SFX toggles and per-mode soundtracks.
Progress
Local storage by default, with optional Firebase-backed accounts for cross-device sync and the leaderboard.
Hosting
Static hosting over HTTPS. There is no server-side game logic to be slow or go down.
How the game is funded
Runner Gacha is free and pays for itself through advertising, served by Google AdSense, plus optional coin packs for players who would rather skip a grind than watch it. Ads are the reason the game has no paywall.
We try to keep advertising out of the way: no ads interrupting a run, no full-screen takeovers between attempts. The rewarded "Watch Ad" button is opt-in and pays 50 coins. You can control ad personalisation at any time through the Cookie settings link in the footer.
