The 24 Game is an excellent game.
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 online game here: Number Solver. This is a good one because you can pick the level of difficulty and a couple play modes. If stumped you can get a solution.
- 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.
