Hi there,
This game consists of 600+ chess puzzles hand picked from the LiChess puzzle database. The puzzles are divided into 3 levels Easy, Medium and Hard.

The easy levels are mate in 1 puzzles which are easy to play. If you are above 1000 elo then you will munch it through in about an hour.

The medium puzzles are mate in 2 puzzles which are of medium difficulty. It should take about 4-5 hrs to complete them for person with 1000+ elo.

For the hard puzzles it can take several days but they are worth the elo improvement.

Try to complete the puzzles in about a week otherwise they might get boring!!
