Twindle: Daily Math Puzzle

Twindle is a daily arithmetic puzzle that challenges your number intuition. Two rows of five numbers share the same four operators (+, −, ×, ÷). Find the one combination that makes BOTH rows equal the target. HOW TO PLAY Tap an operator chip at the bottom to fill the next empty slot. Once all four slots are filled, your answer is checked automatically. Use Undo to take back a move, or Reset to clear all slots. The twist: both rows share the same operators in the same positions. One solution must satisfy two equations at once — that's the Twindle challenge. EXAMPLE (target: 10) Row 1: 6 _ 3 _ 7 _ 1 Row 2: 2 _ 9 _ 2 _ 6 Answer: × − − 6 × 3 − 7 − 1 = 10 ✓ 2 × 9 − 2 − 6 = 10 ✓ FEATURES • Daily puzzle — one new challenge every day, same for all players worldwide • 500 campaign levels — play at your own pace, no time pressure • Streak tracking — keep your daily solving streak alive • Hint — reveal one operator when you're stuck • Share — post your result grid without spoiling the answer • Offline-friendly — no internet connection needed Free to play.
