Stay or Switch is a Monty Hall Problem simulation game. The Monty Hall Problem is a classic probability puzzle that challenges the player to determine the best strategy when asked to select one out of three doors. Behind one of the doors is the prize, the other two only have goats behind them. Once you select your door, the host will reveal the goat behind one of the remaining doors.

This is a math version of the Chinese tile game mahjonng. The goal is to eliminate all the tiles in groups of three that are mathematically-related (via sum, GCD, product etc). Play the tiles carefully and you may be able to clear them all.

This is a pretty straight-forward math game. You need to build equations with the numbers and operators given such that they equal the target numbers. The challenge is in using the numbers wisely so you are able to build all the equations in each round.

In Number Crunch, you need to eliminate all the pieces from the game board by clicking on the numbers in numerical order. As you do so, the pieces will crunch down towards the bottom until you have removed them all. The faster you can complete the task – and the fewer errors you make while doing so – the better your score.

In this Numbles game, you need to search the grid for the various number groups that constitute mathematical relationships. Each round there will be a list provided of the groups you need to find (product sets, odd sets, adding sets, even sets, prime sets, straight sets & GCD sets) and you need to scan the grid looking for each of them, clicking on the constituent numbers to eliminate them from the list.

SwitchBoard is a math and logic game in which you need to toggle the numbers on the board so that all the columns and rows sum correctly.
