Rad og søyle

A number game for two in the browser, in Norwegian and English

Open in your browser

Rad og søyle: a number game for two in the browser, in Norwegian and English. Play the computer at four levels (easy, medium, hard, master), each other on one screen, or print the board; the 4-point bonus that makes it fair was found by solving the game completely, and the page checks that again in the browser.

For: families and anyone who likes a short thinking game
