Numbers is an educational roguelike, that's designed to improve and test your basic maths skills. No calculators are allowed during the game :)

Numbers was created for the 7DRL Contest 2008. You can read the creation log.

Numbers requires Windows and the VB6 Library, which you may have already.

Mini FAQ

Q. Argh! Why is there no 'look' command?!
A. Magical beam effects are random when entered and there's only one monster type, so a look command wouldn't be useful.

Q. I get a message about missing dll's when I run the game. What can I do?
A. Download the VB6 Library.

Q. Can I complete the game without light beam effects?
A. Yes! Light beams are always on intersections, so if you want a challenge, you can move diagonally to avoid them.
