AppBank
Your math calculation skills improve before you even know it. This happens while you solve problems
just to see the beautiful visual effects. It’s an innovative game that makes calculation fun.
iphone-girl
Hamaru is a math game with sparkly and bouncy visual effects. They look like fireworks and are very beautiful.
appmaga.net
The visual effects are reaaaally good!! Plus, the movements are awesome.
appget
It doesn’t feel like a brain training app. It has the lighting effects of a shooting game, and sense of
achievement of a puzzle game. This game has an extraordinary potential.
Hamaru is recommended for gamers of the following types: If you are not one of them, beware.
・You like simple, innovative games.
・You want to become a little smarter while enjoying a game.
・But you don’t really believe it can be that easy.
・You’re not great at doing math in your head, but you’d sure like an opportunity to get better.
・You have a child who’s bad with numbers but loves games.
・You like a beautiful, feel-good user interface!
・You like illumination and other things that sparkle and shine!
・You can't get over laser beams!!!!
.You want to quickly brush up your calculation skills in your spare time.
.You’re looking for an app to help prevent dementia.
.You are interested in words such as: brain training, numbers, math, addition, education, learning, calculation and self-improvement.
If you fit even one of these descriptions, why don't you skip the work of reading some long description, play it, and see for yourself? It is free, after all.
