Domino Effect

 is a reccurring challenge that contestants set up dominos while weaving in and out of traps.

Rules
In the first round, the castaways would race across a series of balance beams carrying a bag of puzzle blocks. The first two castaways to bring all three of their bags would go to the final round in which each player must stack all of their pieces like a line of domino tiles while avoiding ropes that would topple the tiles that were already stacked. Once all of the blocks were properly stacked, the castaway would start a chain reaction which would release a flag. The first castaway to raise their flag would win.
