Stuck on the dartboard puzzle in the Blue Prince Billiard Room or tired to do it again and again? Take a photo of your screen and get the answer — with every calculation step — in seconds. HOW IT WORKS 1. Snap a photo of the dartboard (or pick one from your library). 2. Confirm the alignment — the app finds the board and snaps to the numbers. 3. Read the answer: the number to press lights up on the board, with the full step-by-step math below it. Uncertain readings are flagged for a quick review: tap a highlighted cell to confirm or fix it, and the solution updates instantly. MANUAL ENTRY — ALWAYS FREE Prefer to enter the board yourself? Tap the cells to paint colors, partial fills, the outer-ring symbols and the bullseye. Manual entry is free and unlimited, forever — no account, no ads. FEATURES • On-device photo recognition — photos never leave your iPhone or iPad • Exact fraction arithmetic: results match the game, no rounding errors • Step-by-step solution, in the same order the game evaluates • Outer-ring symbols and bullseye modifiers fully supported • Works on iPhone and iPad, in English and Italian • No ads, no tracking, no account FREE & PRO Photo recognition includes a daily free allowance; Dartboard Solver Pro removes the limit with a monthly subscription or a one-time lifetime purchase.
