D&D 5e Houserule: Minigame: Darts!

The following is a simple little minigame I invented that allows player characters to play darts at the various taverns and bars throughout the D&D world.

How to play darts in D&D:

Each character gets 3 darts to play with for the round.

Each character takes turns throwing a dart at the board. Throwing a dart is a dexterity check, except that 2d10 is used rather than 1d20. Any character with proficiency with darts as a weapon may add their proficiency bonus to this check.

Players score points equal to the result of this check.

At the end of the round, the players add together the scores from all three turns they took.

Players score wins equal to the number of players they bested in a round.

A short game is 1 round, an average game is 3 rounds, and a long game is 5 rounds.

The winner of the game is whoever scored the most wins across all rounds.
