Hi All,

You can access it at:

It is a fully functional app and has support for English, French, Dutch, German, Spanish, Ukranian and Russian.

It has 45 puzzles in total (including 7 examples) compared to the almost 450 puzzles of the paid version. It also only has 4 "checkmate pattern" categories compared to the 12 in the paid version.

Just to mention that 80%+ of the puzzles are unique to the free version so you will not get them all repeated if you decided to buy the full version!!
