# Flappy Bird V0 Template: Fork, Customize & Deploy Your Own Browser Game - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Flappy Bird V0 template is a fully working browser game built on HTML5 Canvas inside a Next.js 14+ React component. It has a real game loop using requestAnimationFrame, AABB collision detection, pipe generation, score tracking, and idle/playing/dead state management. Best for developers learning canvas game loops in React, or anyone who wants a working game to embed in a portfolio or demo. Fork it in 5 minutes; the prompts on this page extend it to leaderboards and power-ups. ## Frequently asked questions ### Is this Flappy Bird template free to use? Yes. The template is a free V0 community template — forking is free. Subsequent AI chat edits consume V0 credits from your monthly allowance. ### Can I use this template commercially? You can use the code for commercial projects — the underlying stack (Next.js, React, TypeScript) is MIT-licensed. Note that 'Flappy Bird' is an intellectual property — if you're publishing for commercial gain, rename the game and change the visual assets to avoid trademark issues with the original. ### Why does the game look blurry on my MacBook? The canvas renders at 1x pixel density by default, which looks blurry on Retina (2x) screens. Fix it by multiplying canvas.width and canvas.height by window.devicePixelRatio and calling ctx.scale(devicePixelRatio, devicePixelRatio). The full fix prompt is in the gotchas section above. ### Why does my fork show a blank canvas in the V0 preview? The game loop runs on the client using requestAnimationFrame. V0's Preview tab is an iframe sandbox — animation should render when the tab is active, but if you see a blank canvas, try clicking inside the preview to focus it. The game renders reliably after deploying to Vercel. ### How do I save the high score between sessions? The template stores the high score in component state only — it resets on refresh. Use the 'Add localStorage high score persistence' prompt on this page to persist the score to localStorage. Read the value in a useEffect (not during render) to avoid Next.js SSR errors. ### Can I add a Phaser game engine to this template? Not via npm in V0 preview — Phaser fails in V0's esm.sh sandbox with 'Attempted import error: phaser does not contain a default export'. If you want Phaser, load it via a CDN script tag using Next.js Script with strategy='beforeInteractive'. See the gotchas section for the exact fix prompt. ### Can RapidDev extend this game template? Yes. RapidDev takes V0 game starters into production — adding leaderboards, social sharing, mobile-optimized canvas rendering, and Vercel edge deployments for fast global load times. ### Does this template work on mobile? Yes, with a caveat. The KeyboardTouchHandler includes a touchstart listener, so tap-to-flap works on Android Chrome. On iOS Safari, you may need to add cursor: pointer to the canvas element and use { passive: false } on the touchstart listener — see the gotchas section for the exact fix. --- Source: https://www.rapidevelopers.com/v0-template/flappy-bird © RapidDev — https://www.rapidevelopers.com/v0-template/flappy-bird
