Formula is a perfect game for schools, vacations or at home. It is primarily a fun game, but at the same time it has something unique about it: it is a maths game. Children are not aware that they are doing maths; they are just playing a fun game.
The goal of the game is to be the first to get rid of all your cards. To get rid of the cards, a formula (or equation) has to be formed as well as the answer has to be given.
The concept is simple and the possibilities are endless. Whoever is best at math doesn't necessarily win, so it's fun to keep playing.

The expansion pack for Formula - Base Game adds negative numbers, fractions, square and square root to the game. It can be made as challenging as you want. You do not necessarily need to add all cards to the base game.
Please note, that you do need the base game to use the expansion.
