I'm generally bad at this sort of thing, so I have a ton of "Untitled Dice/Card/Property Expansion Project (month,year.)" And frankly, that's getting annoying because I don't remember what I did when.
Here's the most recent thing I'm working on: two players roll dice of their color and place them on a bingo board with a neutral die in the middle. The player who has more of their dice in a row or column will score points if they have pairs, several of a kind or so on. However, a row or column with no matching dice will cause havoc for the owner as whoever has more of these "orphan" rows will lose half of the points accumulated in that round.
Any ideas will be taken into consideration, and many thanks.
