One app for chess lessons, puzzles and games.
Trainstein is a game-like chess platform for young players. Kids read short lessons written by our titled coaches, practise puzzles sorted by theme, and test every new idea against friendly monsters. Behind it are more than 10 years of teaching thousands of kids at Trainstein Chess College.




Beat the monster
6 worlds. 36 monsters to beat.
The monsters get stronger world by world, so your child keeps meeting a new challenge — and can try again as often as they like.



Learn from real lessons
5 books, 200+ lessons, designed by our titled coaches.
Five books of chess lessons written by our coaches, from the very first moves to real strategy. Try a sample lesson on the board.




Race the clock
Three minutes. How many can you solve?
3-minute, 5-minute and Survival modes, across 50+ themes and theme mixes, so kids can practise what they find hard until it becomes a strength.


Play mini games
9 planets. 70+ games.
Nine planets, each built around one piece or one skill. Kids learn how the pieces move by playing, not by memorising rules.

- A blue Chesspedia lesson book.
Read a short lesson and learn one new idea. Our coaches break chess into small steps, so each lesson teaches one thing at a time.
- A Puzzle Rush crystal.
Solve puzzles on that idea until it feels easy. Puzzles are sorted by theme and level, so practice stays on the skill your child is learning.
- Thundermaw, the purple dragon of VS Bot.
Use it in real games against the monsters. The monsters get stronger world by world, so every new idea is tested in a real game.
- A chessboard under a magnifying glass.
Look back at mistakes and learn what to try next time. Going over a wrong move is how our coaches turn a mistake into the next lesson.
The same learn – practise – play – review loop our coaches use in class.
Safe for families

You can see what your child learns.
Questions, answered.
What age is it for?
Any young player, from their very first move. Lessons start from how the pieces move, so beginners are welcome.
How long should my child play?
Short sessions work best. A Puzzle Rush round is 3 minutes; 10 to 15 minutes a day is plenty.
Does my child need to know chess?
No. Chesspedia starts from the very first moves, and the monsters start easy.
Can I see my child's progress?
Yes. You manage your child's account, and it shows their best puzzle scores and the monsters they have beaten.
