The game is exciting and develops logical thinking, as well as helps to improve memory.

Ads interfere with the gameplay

There are comments to the interface: it is not always convenient to use notes, the same numbers are not highlighted, there are problems with loading, etc.

There is not enough opportunity to start a competition and see your rating

Sometimes the game allows only one solution and does not take into account the other correct options.

In general, the game trains the brain well, but some functions need to be improved.
