How it works
Private prediction pools with play money. Bet on your friends, hide it from the subject, and let the scoreboard settle who knows everyone best.
Quick start
Step 1
Start a room
Name your pool, invite your crew with a code. Everyone starts with the same stash of play money.
Step 2
Post a slip
Write any Yes or No question about anything. Tag the person it's about if you want it lowkey.
Step 3
Trade and talk trash
Everyone buys Yes or No. Odds shift as the room piles in. The scoreboard updates in real time.
The rules
Every pool uses fantasy cash — no real money involved. When a pool is created, the admin sets a starting balance (for example, $1,000) and every member gets the same amount. Your wallet is separate in each pool you join.
Any member can post a Yes or No prediction about anything — group trips, personal goals, hot takes. Set an expiration date, tag the people the bet is about, and optionally mark it lowkey or anonymous. Once posted, the room can start trading.
Buy Yes or No shares on any open slip. Prices move between $0.01 and $0.99 as the room trades, reflecting what the group thinks will happen. You can sell shares you already hold to lock in gains or cut losses. Bigger orders move the price more.
Tag someone as the subject and turn on lowkey mode — they won't see the slip or any trades until it's settled. Everyone else trades normally. When the slip resolves, the subject gets a reveal showing the question, outcome, and who bet what.
When a slip expires, the person who posted it (or the pool admin) picks the winning side. Winners get $1.00 per share; losers get nothing. A slip only pays out if at least two people traded on opposite sides — otherwise everyone gets a full refund. If the creator traded on their own slip, an admin must settle it.
The scoreboard ranks members by net worth: your cash plus the current value of any open positions. It updates as prices move and slips settle. Bragging rights are the whole point.
