How can I use the Power Cards if there are 4 of them (usually there is only one card per color).Even if the right symbol was shown I couldn't click on them. Can you please help me Thx!!

One card shows up each round. Three need to used during the round prior to making a connection choice. One can be used at round end. I just click the card icon to activate before making a route connection.

1. Get a free split in the track - treat your current planned connection as a split line
2. Repeat the same connection shape (circle, square, etc.) although if you pick a wildcard station type then the repeat will be of the same shape not a further wildcard
3. Get and use as a wild card

At round end:
4. Double up the point value of an already placed connection
