All-time
Best verified run per wallet, ever · this board does not pay
The round above resets every round and is the one that splits the pool. This one keeps going, so a score you set at 3am is still here at noon. Top 10 counts rounds finished in the paying ten.

About
flappybird.cash is a free, browser-based Flappy Bird with a server-verified leaderboard and a prize pool. One tap to fly, unlimited attempts, no download.
How it works
- Play free. No entry fee and no wallet needed — play as many rounds as you like.
- Enter your Solana address to be ranked. Guests can play but never appear on the board.
- The server verifies every run. It owns the course, hands you the pipes only as fast as real time allows, then replays your exact taps through the same simulation. Your device never decides your score.
- The top 10 of each round split the prize pool, paid to the address you entered. The live countdown under the game shows when the current round ends.
Provably fair
The simulation is fully deterministic: the same course and the same taps always produce the same run, down to the last sub-pixel. It exists in three implementations — the Python server, a TypeScript reference, and the JavaScript your browser runs — and all three are pinned to the same 102 golden test vectors. If they ever disagreed, the build would fail rather than pay out a wrong number.
The course seed never leaves the server, and pipe geometry is revealed progressively as real time passes. That is what stops anyone solving the whole course offline and submitting a perfect trace instantly.
The prize pool
The pool is 50% of $flappybird creator fees on pump.fun — a share of real trading activity, not a fixed rate. On a quiet round the pool is small, and it can be zero. This is a game, not an investment; see the Terms.
A tribute
This is an independent fan homage to the original Flappy Bird. It is not affiliated with, endorsed by, or connected to the original creator.
How to Play
Keep the bird in the air and thread the gaps between the pipes. Simple to learn, ruthless to master.
Controls
The goal
- Each flap gives the bird a small upward push; gravity pulls it back down.
- Fly through the gap in every pipe. Each pipe you clear adds +1 to your streak.
- Touch a pipe or the ground and the run ends. The ceiling is not lethal — you are simply blocked by it.
Getting ranked
- Paste your Solana address on the start screen — it is optional, and you can play without one.
- Your best verified run of the round holds your leaderboard slot. Ties break in favour of whoever got there first.
- One address = one slot. Running several addresses to grab extra slots gets you banned.
Tips
- Tap in a steady rhythm rather than mashing — small, frequent flaps are easier to control.
- Aim for the middle of each gap so you have room to correct.
- Look ahead to the next pipe, not the one you are passing.
- Stay calm after a near miss; panic taps end most runs.
Privacy Policy
Last updated 28 August 2026
We keep this simple: we collect as little as possible, and we never ask for anything that could move your funds.
What we collect
- Your Solana address — only if you choose to enter one. It is used to rank you and to send any prize you win.
- Run data — your tap timings and the resulting score, submitted so the server can replay and verify the run.
- A device fingerprint — a short hash of coarse browser properties (screen size, language, timezone). It is used only to spot one machine farming many addresses.
- Technical logs — standard request data such as IP address, browser type, and timestamps, kept for security and anti-cheat.
Stored on your device
Your best score, your mute preference, and the Solana address you last entered are saved in your browser's local storage, so you do not have to paste it again. They stay on your device, and clearing your browser data removes them.
What we never ask for
We will never ask for your private key, seed phrase, or password, and we do not collect your name, email, or identity. A public wallet address is all that is ever needed.
Sharing
- With the infrastructure providers that host the game and its API.
- On Solana, a public blockchain: prize payouts, the pool address, and winner amounts are visible to anyone and are permanent.
We do not sell your data.
Cookies
We do not use tracking cookies. The only browser storage we use is the local game state described above.
Your choices
Play as a guest with no address to stay anonymous, or clear your browser storage at any time to reset your saved score and address.
Changes
If this policy changes, the date above is updated. Continuing to play after a change means you accept the new version.
Terms of Use
Last updated 28 August 2026

The game
flappybird.cash is free to play and provided as is, without warranties of any kind. We may pause, change, or discontinue it at any time, and availability is not guaranteed.
Fair play
Only server-verified runs are ranked. Automating play, tampering with the client, exploiting bugs, or running multiple addresses to take more than one leaderboard slot will void your scores and may result in a ban. Runs that look automated are held for human review before any payout.
Prizes
- The prize pool is funded by $flappybird creator fees and varies with trading activity. It is not guaranteed and may be zero.
- Prizes are paid on Solana to the address you entered, by hand, after each round is closed.
- On-chain transactions are irreversible. We cannot recover funds sent to an address you do not control or lost to a compromised key.
