iPhone Giveaway of the Day - Anzan Sense

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)
