The puzzles need to be double checked. The suggested move (tip) was not allowed in 1 puzzle. And one time I promoted to a Queen but it demanded promotion to a Bishop?
In Practice mode the arrows should be optional, I also like to play with the Coach only. Sometimes the best move (most bright green arrow) is a bad move according to the Coach.
The Computer Mode is supurb though! The chess engine almost plays like a human. I love the sounds too. You can choose from many chess boards, peaces and you can even choose the button theme and the background of the app, fantastic!
The analysis bar only works during the active match, but it should also work when analysing the finished game.
But make no mistake: this app is definately worth the money. It’s a gem.
