The Marshmallow Experiment
Eighteen double-sided cards, each with 12 marshmallows of either pink or white colouring. All you have to do to win is have the longest single uninterrupted vertical line of marshmallows. You can declare your winning line at any time, but as soon as you do, your opposing player can look through ANY of the remaining cards and play it, potentially beating you. Can you resist calling out your winning line?

Buried Puzzles Included
You read that right - each mini-game has a puzzle buried within it - which vary from the elementary to the head-scratching. There is a delightful game-related mental reward when you solve each of the puzzles contained within each game.
Wallet Plus Cards
These are quite simply the most versatile card games - housed in their own wallet, they can fit comfortably into a day bag, rucksack, suitcase or lunchbox.
