Your objective is to create large domino chains as quickly as possible. The chain must start at the 'entry' point and end at the 'exit'. You can create multiple chains, loops, and use different colors, whatever you like.
You are allocated a certain amount of time and a set number of dominoes to use to get through each level. Using all the required dominoes is not enough - they all have to fall over when pushed at the end of a round.
Click 'undo' to remove the last placed domino (unlimited times) or 'delete' to specifically select and remove a domino or 'clear' all the dominoes.
Watch out for obstacles - you will have to work around them, except for the bridge - you can place your dominoes over it.
When you’re done placing your dominoes, click the first domino to start the chain reaction!
