Move numbered tiles so they touch. Click on a numbered tile that's around the MNUM board so it moves to the furthest free space. In MNUM, numbered tiles have to connect/touch in basic directions (top, bottom, left, right; no diagonals). If the numbered tile has number 2, 2 numbered tiles with number 2 have to be next to each one. If it's 3, 3 tiles numbered 3 have to be next to each one. And so on. If those numbered tiles touch, they disappear and points are added. If more numbers than necessary get connected (for example 4 threes), the added score gets multiplied.
The concept was taken from Tetris. It's a "little" different, but the idea is from that... Yet another tile-matching puzzle game...
Stop reading if you want to find out yourself! Best way to play is to match small numbers first and later go for larger numbers. I’m sure you can beat my friends with score as high as 20.000.
It looks like a cross, so let’s add a prayer: “Big MNUM! Give me the good brain to play this game well without any deity, just myself, based on my skill I’ve gained ... playing this game.” ;)
