Hi, my name is Shachar Lovett, I live in Israel, and I'm currently a MSc student in computer science.
This page holds a collection of beautiful mathematical and logic problems, some of which are easy, and some are very hard. The puzzles are graded either easy(*), medium(**) or hard(***).
Currently, only the problems are given, and not their solutions (although I've solved all of them), which prevents the easy option of looking at the answers, and so makes you work your way to the solution.
For any questions regarding the solutions or hints, my email is at the bottom of the page. also, any suggestions for new puzzles will be accepted gladfully.
I welcome you to the wonderful world of puzzles.
