いっこふえた Nova Dot

Dots flash on screen, vanish, and come back. But one dot has been added. Tap it. That is the whole game. WHY IT FITS A SHORT BREAK Three lives, sixty questions maximum. On the normal level, even your best run takes under six minutes. One stop on the train, a queue at the register, waiting for a lift - you will never be cut off in the middle of something. If you close the app mid-run, your score so far is kept and the run resumes from the same question. ONE HAND, QUIET BY DESIGN Tapping is the only input. You can play with one thumb while holding a strap. Sound effects are short and quiet. The iOS silent switch is respected, so the game stays silent when your phone is, and other apps keep playing - your music is never interrupted. You can turn sound off in Settings and play with haptics alone. DIFFICULTY THAT STAYS FAIR It starts with three dots. As you progress there are more dots and less time to see them. The count stops at fourteen and never goes higher - beyond that it becomes luck rather than memory, and that is not the game we wanted to make. FROM QUESTION 21, IT IS NOT ALWAYS AN EXTRA DOT Later rounds mix in questions where one dot has moved somewhere else instead. The number of dots does not change, so counting will not help - you have to remember the shape they made. What you do stays the same: tap the dot that does not match. MAKE IT YOURS Three difficulty levels: easy, normal and hard. Easy gives you longer to memorize, which also makes a run take a little longer. Five background colours. Sound and haptics each switch on and off. YOUR RECORD Today's best and your all-time best, kept separately for each difficulty. When you are one dot away from a new record, you will see it - and want one more run. HOW TO PLAY 1. Dots appear. Remember where they are 2. They all vanish 3. They come back, with one extra dot (later on, one may have moved instead) 4. Tap the one that is different from what you saw That is it. There is nothing to read first. --- This app displays advertisements. You can change your ad preferences at any time in your device settings.

Verdict
The clearest difference is update cadence: いっこふえた Nova Dot at every 4 days against Math Grid's fortnightly. Math Grid's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and in-app purchases there is nothing between them.
