Endless puzzles, honestly graded
Every puzzle is new and has exactly one solution. Its level is set by the solving techniques it actually needs, so a Hard puzzle is hard for a reason.
-
Hints that explain the logic
A hint names the technique and where to look, then highlights the pattern and explains it. It only fills in the step when you ask.
-
A daily puzzle
Each day brings one puzzle per level, the same for everyone. Solve one a day to keep your streak going.
