Square Wisdom: 200 CalcuDoku puzzles
My first CalcuDoku book can now be purchased on Amazon!
The book contains 200 puzzles ranging in sizes from 5×5 to 9×9.
- 136 puzzles are with all operators, evenly split into the standard five difficulty levels: EASY-COOL-THINKER-BRAIN-IQ, but there are also a couple INSANE
- 64 puzzles are with the (significantly) reduced number of operators, mainly THINKER-BRAIN-IQ
Enjoy!
