You have 7 tries to guess a sequence of 5 dominos.
Use the domino keyboard to add 5 dominos to the tray and submit your guess.
Each guess is analyzed and its dominos and the domino keyboard are coloured.
A red domino indicates that domino is not in the sequence.
A yellow domino indicates that domino is in fact in the sequence but in a different position.
A green domino indicates that domino is in the correct position in the sequence.
Keep submitting guesses based on the results of your previous guesses until you get all green dominos.

Good luck and have fun!
