To be honest I put this up in a bit of a rush, and didn't expect much attention with it, so thanks so much for the feedback! I really appreciate it when people connect to one of my weird old designs.
- I've modified the rules so you deal 4 cards to each player.
- I've added a rule about what to do if you can't place a card. It gets returned to the deck, allowing you to make one and two digit numbers.
- I've removed the rules from the description to remove confusion.
