Oh Hell Scorekeeper is the ultimate companion app for the classic card game "Oh Hell". Designed specifically for iPhone and iPad, this clean, modern app automates all score calculations, prevents math mistakes, and tracks detailed player statistics for you to share with your playing partners. KEY FEATURES: • FAST & FLEXIBLE GAME SETUP Quickly add players to your roster, drag-and-drop to match the seating order at your table, and select the starting dealer. Supports 2 to 10 players. • TWO-PHASE SCORING WITH VALIDATION Enter bids in Phase 1, then tricks in Phase 2. The app automatically calculates scores according to standard Oh Hell rules: 10 points for a successful bid plus the bid amount, or negative points equal to the difference if you miss. • AUTOMATIC RULE ENFORCEMENT Never argue over incorrect bids or tricks again! The app enforces the game’s core rules: - The "Hook" Rule: The sum of all bids in a round cannot equal the number of cards dealt (ensuring someone always misses). - Trick Validation: The total number of tricks won must exactly equal the number of cards dealt in the round. • REAL-TIME SCORE PREVIEWS See potential scores update in real time as you type trick counts, showing exactly who is in the lead and how many points they stand to gain or lose. • INTERACTIVE SCORECARD WITH CORRECTIONS Need to fix a mistake from three rounds ago? Open the detailed scorecard, tap any previous round, and correct the bids or tricks. The app will instantly recalculate all subsequent round scores and updates. • PERSISTENT GAMES & AUTO-SAVE Life happens! If you close the app or take a call, your game is automatically saved. Resume any active session from the main menu. • IN-DEPTH PLAYER STATISTICS & BADGES Track your group's performance over time with detailed metrics: - Win/Loss Ratio - Bidding accuracy and most common bid amounts - The "Oh Hell" Multiplier (dealer vs. non-dealer success rate) - Fun Achievements & Badges: "8-Trick Sweep" (winning all tricks in an 8-card round), "The 69 Club" (finishing on exactly 69 points), and "Losing Big" (losing 3+ points in a single round). • PRIVACY-FIRST & OFFLINE-READY Oh Hell Scorekeeper does not collect, transmit, or share any personal data.
