Master of Numbers

Blue numbers mean grow, red numbers mean game over - that's the whole tension running through Master of Numbers. You're not just sprinting down a lane, you're doing arithmetic on the fly, absorbing every value smaller than yours and steering hard away from anything bigger and red.

If you liked the idea behind Man Runner 2048, where the numbers on your back decide whether you live or die, this scratches the same itch but adds saws, bridges and ditches to the mix. One bad decision near a red number and you're starting your run from zero again, literally.

This is one for the player who actually enjoys a bit of mental math under pressure - the kind who'd rather calculate their next move than just react to it. It's a genuine Skills games pick as much as a Running games one, since timing your jumps matters just as much as knowing which numbers are safe to touch.

It runs free in the browser on phone or desktop, no install needed, so you can test your math reflexes on a break and pick it up again later without losing anything but your last number.

Reach the finish line while typing the maximum possible number. Absorb blue numbers smaller than your current one to grow bigger, but avoid red numbers larger than yours - touch one and you lose your number, forcing you to start the run over.

Along the way you'll need to dodge electric saws, cross bridges and jump over ditches without slowing your math brain down.

Tip: don't grab every blue number blindly - check the size difference first, since a tiny gain isn't worth the extra risk if a red number is lurking right behind it.
