Puzzles you solve with your head, not with luck.
Small number puzzles for your phone and PC. Every one has a single answer, and you can always reach it by thinking it through.
Suguru is coming soon to Google Play and the Microsoft Store.
Tap an empty cell, then a number. Matching numbers may never touch, not even corner to corner.
The games
One out soon, three more on the workbench. Each one is a puzzle you can finish on a bus ride.
Suguru
Fill each shape with the numbers 1 up to its size. Two matching numbers may never touch. Easy to learn, and the Expert levels will make you stop and stare.

Fill the grid so each cage adds, subtracts or multiplies to its target.
Killer Sudoku
Sudoku with dotted cages that tell you their sum, and almost no given digits.
Jigsaw Sudoku
The classic rules, but the boxes are bent into odd shapes, so the usual shortcuts stop working.
