I've always believed that daily mental exercise has real value. QuRealm is my attempt to make that fun.

What is QuRealm?
QuRealm is a free daily math puzzle. Every day at midnight UTC, a new puzzle is generated — the same one for every player in the world, regardless of language or location.
The concept: given 4 numbers, reach a target using +, −, ×, ÷. You can chain operations. It sounds simple. It isn't always.
QuRealm supports Easy and Hard modes. Easy keeps targets between 10-50. Hard pushes to 50-200, requiring more creative chains.
