The twist to the game is that there are fewer of some colors than others, both in cubes and cards. For example, there are thirteen red cards (values 1-13), but only five gray cards (values 1,4,7,10,13) making some races more challenging to complete and limiting a player's options.
This was an unusual game of Balloon Cup as neither Carol or I collected any prize cards for the longest time. We just went back and forth amassing a huge amount of cubes, but neither gaining enough to claim any prize cards. Finally, I won my third gray and my fifth green cubes (as above) in one turn to get their prizes and shortly thereafter collected a fourth blue cube for the win.
Coming up: We battle for ancient Greece with ships, swords and Gods in Hellas.
