15-Minute Up or Down
Pick BTC, ETH or SOL and guess the next 15-minute candle. Paper points reset daily — no wallet, no cash value.
Simulation for entertainment. Points have no cash value. Not gambling, not investment advice.
How to play
- Choose BTC, ETH or SOL, pick up or down, and lock a paper-point stake before the next 15-minute UTC candle opens.
- When that candle closes, we compare its close to its open. Correct calls pay double the stake; wrong calls lose the stake.
- You receive 1,000 paper points per UTC day in local browser storage. Points cannot be bought, redeemed or transferred.
Market data and void rounds
Candles are loaded through our server from Binance public klines, with Coinbase Exchange candles as fallback. This is a simulation for entertainment, not live trading.
A round is void and refunds your stake if candle data is missing, malformed, incomplete, or both providers fail.
Frequently asked questions
Is this real money or gambling?
No. Paper points have no cash value and cannot be purchased or withdrawn. The page is a simulation for entertainment, not investment advice.
Which candle am I betting on?
Your locked guess applies to the next 15-minute UTC candle for the symbol you selected. Settlement uses that candle's open and close from the data providers.
Where do prices come from?
Our Next.js route requests Binance 15-minute klines first and falls back to Coinbase Exchange if needed. Errors are surfaced instead of silently ignored.
