OddsBoy

Friends, one phone, one prediction game. Results stay secret until everyone has picked. All agree? A contrarian CHANCE appears. Points are record-only — no real money.

OddsBoy is a local score-calculation app for prediction games among friends.

Pass a single iPhone around the group and enter your prediction privately, without others seeing. Score estimates and results stay hidden until everyone has finished.

Points are a record-only score inside the app. They cannot be purchased, redeemed, or transferred. The app does not handle cash, redeemable points, prizes, or online wagering. Like a Mahjong score-keeping app, it is simply a tool for tracking points in friendly play.

■ Great for

• "Who's going to win?" at parties and get-togethers
• Predicting winners while watching sports or game tournaments
• Light, friendly contests with family and friends

■ Features

• Private predictions: pass one phone around and everyone picks secretly. Nothing shows until all are done
• 2–4 options: not just "Team A / Team B" but draws or multiple choices too
• Contrarian CHANCE: if everyone predicts the same, the round doesn't count. Next time the options no one picked get "CHANCE 10% DOWN," making contrarian picks easier
• Split pool: a calculation style where larger entries don't lose out, settling only within matched amounts
• Score updates and history: apply results to points and keep a record of each game and its breakdown
• Fully local: no servers, no account, no internet needed. Data stays on your device
• No ads / no tracking / no in-app purchases

■ Before you use The points and scores in this app are record-only numbers on your device. They have no monetary value and cannot be redeemed. They cannot be exchanged for cash, redeemable points, or prizes.
