If you've got the memory of a goldfish then one of the best ways to sharpen your powers of recall is by playing matching pairs. Twice presents a novel version of the classic game for your mobile phone.
As with the classic game, the object of Twice is to flip over the face-down tiles and remember the pattern in order to match it to another tile. You score points every time you make a pair and must clear all the tiles on the board to finish the level.
There are three different game modes in Twice to keep you occupied. There's 'Sly', which gives you a limited amount of time; 'Agile', which limits your number of attempts; and 'Smart', which has no limits at all.
The presentation of Twice is very pleasant. The game combines fantastical graphics with dreamy sound effects and magical music to create an enchanting, tranquil gaming experience.
It might not be the most original game ever, but Twice will help you boost your memory scores while you're sat on the bus.
