Tower of Hanoi online is a warm wooden puzzle toy come to life on screen: tap a peg to lift its top disc, tap another peg to drop it, and rebuild the tower on the marked peg in as few moves as possible.
300 levels grow from the classic 3-disc tower to scrambled starting towers, a rescuing 4th peg, colour-locked pegs and discs, and a final two-tower swap with 7-8 discs.
How to play
- Tap a peg to pick up its top disc.
- Tap another peg to drop the disc there — only a smaller disc may land on a bigger one.
- Rebuild the whole tower on the peg with the star in as few moves as the counter shows for 3 stars.
What your child learns
- Recursive planning: solving a small tower first, then the big disc, then the small tower again.
- Reading a scrambled position instead of repeating a memorised pattern.
- Working within extra resources and constraints (a 4th peg, colour rules).
The science behind the games
Every Dad4Kids game is built on one simple truth: children want to play, not study — so we turn learning into a game worth replaying. The method draws on peer-reviewed research in game-based learning, motivation, and how memory works.

FAQ
What is the Tower of Hanoi puzzle?
A classic logic puzzle: move a stack of discs from one peg to another, one disc at a time, never placing a bigger disc on a smaller one.
How many discs and levels are there?
300 levels, from 2-3 discs in the first lessons up to 7-8 discs in the finale, plus 4-peg and colour-locked variants.
Is there a time limit or can I lose?
No timer and no losing — mistakes are gentle, moves never run out, and stars reward the shortest solution instead of speed.
Can I undo a move?
Yes, undo is free and unlimited — plan ahead, try a move, and take it back any time.
