Liar's Dice with Friends

Each player starts the game with 5 dice. Players roll their dice and keep them hidden. Taking turns, each player makes a claim, which is an assertion about how many dice of a particular kind exist among ALL of the players, for example "5 fours." Each player can only see their own dice so they are guessing about the others. After a claim is made, the other players either accept of challenge the claim. When a claim is challenged, dice are revealed and counted. If the claim was true then the player who made the challenge loses one die. If it was not true, the player who made the claim loses a die. Play continues until just one player still has dice and they are declared the winner!
