Rizo Puzzles

Number puzzles shouldn't look like a tax return.

Riso Puzzles is a small collection of classic number games designed to look like a risograph print. Every number has its own ink. Take a pair in Number Match and it gets stamped out. Finish a box in Sudoku and it gets a halftone layer, so the board turns into a print as you solve it.

Daily sheets. There's a new Number Match and a new Sudoku every day, and everyone gets the same ones, so you can compare scores with friends.

Streaks. Print either daily to keep your streak going. The week strip records which games you finished each day.

Endless mode. Play as many as you like. Number Match gets a row bigger each stage, and Sudoku comes in Gentle, Steady and Tricky.

How to play Number Match: pair two numbers that are the same or add up to ten. They need to be touching across, down, diagonally, or from the end of one row to the start of the next, and cleared cells in between don't count. Clear a whole row and it's torn off the sheet. Stuck? Add numbers copies everything left to the bottom of the sheet.
