Thee bonus game is 'Matching Pairs', a traditional memory game: by default, at the lower level you simply match up pairs of pictures, while at the intermediate and higher levels you have to match up sums and their answers. However, if you wish, you can select to use the simpler game at any level.
Note: The 'Recognising Fractions' section always uses the simpler, picture matching game.

Matching Pairs (Pictures)
Each panel hides a picture. The panels are clicked in pairs, the aim being to match up pairs of identical pictures. If correct, the pictures remain visible, and you move on to the next pair. The aim is to reveal all the pictures with the lowest possible score. Best (lowest) scores you can be entered into the 'Hall of Fame'.
This is the default bonus game at the lower level.

Matching Pairs (Numbers)
Here the game has the additional twist of teaching as well as improving memory! Each panel hides either a sum or an answer, at the current level of difficulty. The panels are clicked in pairs, the aim being to match up the sum and its answer (with matching color). The aim is to reveal all the numbers with the lowest possible score. Best (lowest) scores you can be entered into the 'Hall of Fame'. Note that there are different best scores for each skill.
This is the default bonus game at the intermediate and higher levels.
