Brain Games

This is the free of charge and ad-free version. It has minor limitations in settings or levels of difficulty, which of course are not present in the supporter version (+ version).

The app currently contains the following game modes:

• Maths: mental arithmetic for adults (basically for any age after primary school)

(Different tasks up to roots and powers.
Easy to start with but getting harder quickly when advancing.)


• Maths: mental arithmetic for kids (primary school level)

Numbers up to 10 or up to 20, plus, minus, multiplication, division, `point-before-line` tasks.


• a sound reaction and concentration game/test


• a word riddle, similar to `hangman`
(German or English words can be selected)


Random choice out of more than 130.000 Maths tasks - there won`t be 2 identical runs for you!

All game modes provide several difficulties which makes them suitable for elder kids as well as for grown-ups.

Each game has a separate leaderboard, so you can challenge yourself or your family members over and over again.

Most games can be interrupted ANYTIME and continued later due to automatic saving.

Try everything in the free version if you like - it has only few limitations.
