The 24 Game is an excellent game.
It has been around for a long time and we have the board/card game in the Math Resource Office at WIU.
I’ve recently really come to enjoy it because I could learn from it (and get better at it/learn strategies, and not just get frustrated). The two main reasons (tools) it has become an enjoyable learning experience for me are:
- There is a great iOS app: MADS 24.The app gives you practice or timed play. There are variations, but I prefer the good old 24. It will give the answer if you can’t get it – which is a learning experience if you don’t use it too much. 😉
- There is an online 24 solver at http://24solver.us-west-2.elasticbeanstalk.com/ It is very clean and nice. Again, it can be used as a learning tool.
