Want a deadly challenge? Try The Rock Game, a version of the ancient puzzle Nim. It appears to be very simple, but can you beat it?

The objective of this game is very simple: do NOT be the one to take the last rock. This can be very tricky and deceivingly hard. The rules are also very basic: you must take at least one rock every turn, and you may not take rocks from two separate rows in the same turn.

Try not to get stuck between a rock and a hard spot!

Remember me?

I was one of your math students at TWAI. I also went and helped you dig holes and pour concrete at the house you were building. I played this once and remembered you showing us that if they know how to, the player that goes second will always win, can you add an option for the player to go after the AI? Also wanted to reach out and say hi

It is actually the person who goes first that always wins unless you make a mistake.


The game rocks

Fun game. Simple, yet challenging. And has great background music and background image used.
