Numbers flash one at a time and you add them up in your head. A simple but deep flash mental math game. Three modes and flexible settings train your calculation, focus and working memory. Three modes - Standard: add the flashing numbers (the basic mode) - Listen: numbers are not shown, they are spoken aloud. Listen and add - Dual: two columns flash at once. Enter each total Settings - Difficulty: 4 levels (changes the flashing speed) - Digits: 1-digit / 2-digit / 3-digit - Numbers per problem: 5 to 20 - Problems per session: 3 to 15 Extras (optional spice) - Letter noise: hiragana / kanji mix in. Ignore them and add only numbers - Conditional rules: star doubles your total, diamond triples it, triangle subtracts - Photo distraction: your own photos flash in briefly (with permission) Records Your correct count and accuracy are tracked. Beat your best accuracy per mode and difficulty! No ads. No in-app purchases. No data collection.
