An example board with the final prototype. I started with having 1 tile in your hand at a time, but players didn’t have enough options. Eventually I settled on 5 in your hand, but they were unwieldy to hold, so I added a shield so you can keep tiles hidden. Then I put the master tile list on the shield so you can look to see if a piece you need exists and if it has been played yet. That mitigates some of the veteran player advantage.
