Hi there! Look at my new site at rooms.jmpup.com.
This is an online puzzle game, which gives you infinite puzzles of a type, introduced by Raymond Smullyan in his book "The Lady or the tiger?".
I hope you will enjoy it, it is playable equally nicely from a mobile or a PC!
The puzzles are becoming harder and harder as you solve them, so a good idea would be to have a piece of paper and a pen nearby.
