"A game that simulates the working of the stock market a little, where you need to bid carefully."
Bank It is a curious game, in which luck and randomness play a large part. You enter the world of finance as if you were an authentic stock broker.
In Bank It you must acquire different shares that are offered in different plays, but you need to use your astuteness, and be clear how much you want to invest at each moment. You could win or lose big, because sometimes you only get bombs, which explode and destroy all the money you invested there.
Therefore in Bank It it is wise to bid with caution and not let greed cloud your judgement.
