In Brain School you have to discover a code, which is made up of cards. The cards used are from a standard 52 card deck.
You find the code by asking questions such as
" Where is the card with the lowest value? "
" What is the sum of all the spades cards? "
Asking questions cost 'clues', which you have a limited amount of.
Once you find the code you can transform the remaining clues into new rules for the next rounds.
The questions will rarely give you a direct answer to one of the cards, instead you will need your logic and deduction skills to figure out what each card is.
The next round will have more cards in the code, so it will be more difficult to find the code. Reach and solve the final round to win!
