Double Dragon 2 walkthrough (SNes): Mission 73 - %nomNiveau%

Start by taking the topmost elevator and placing it on the upper floor between the 2 delayers (photo 1); stay at the top and swap the rightmost yellow domino and tumbler, then place the tumbler - the one just below - to the left of the delayer (photo 2); finally, place the 2 center bottom dominos so they surround the stopper (photo 3), and push the top elevator!
