Build bridges with the fewest number of blocks. Combine expensive smaller blocks and trade them for cost-saving larger blocks. The goal is to keep the cost as low as possible.

Moving Blocks
Click and drag blocks to drop them anywhere along the gaps in the bridge. At first, you will only be able to place blocks. When you have enough smaller blocks to trade for a larger block, you can make a trade.

Trading Blocks
Select the blocks you want to trade then click the "trade" button.
You may only use blocks that are in the same row for trades.
