Simple Dice Gambing Game for 5e

This is how I handling dice-gambling in my games. Its simple, incorporates character skill but also the players to play with the bets.

Depending on the region, this game is called Hafling Toss, Knuckle Toss, or sometimes Pirate Bones.

This game requires 3 or more players (PCs or NPC), and each player requires either 3d6, or a d20.

Roll Initiative to determine the first Bet.

Step 1 -The player who won Initiative determines the Bet for that roll (usually an amount of money).
(Player 1 bets 10gp).

Step 2 - All other players much match the Bet to play.
(Player 2, Player 3 and Player 4 must also bet 10gp to play. There is now 40gp in the pot).

Step 3 - All players roll their 3d6(or d20), adding their Perception Skill*. They may also add +2 if Proficient with Tools: Gambling Dice.
(Player 1 rolls d20 plus Perception Skill for a total of 16.
Player 2 roll d20 plus Perception Skill plus 2 for being proficient in Dice. Total 7
Player 3 rolls d20 plus Perception for a total of 22!
Player 4 rolls d20 plus Perception plus 2 for for being proficient in Dice. Total 12)

Step 4 -The player with the second highest total wins their Bet back. The player with the highest roll takes the rest. In the event of a tie for the highest roll, the money remains in the pot and is added to the next roll. In the event of a tie for the second highest roll, all tied players get their bets back.
(Player 1 wins back their 10gp. Player 3 wins the rest of the 30gp. Players 2 and 4 lose their bets).

Step 5 -The next player (go clockwise) then calls the next Bet, and so on around the table.
(Player 2 calls the Bet for the next roll).

*If the DM allows, players who want to cheat may use Sleight of Hand or Deception, rather than Perception for their roll. However, in the event that player rolls a natural 1(on d20 or 3on  3d6), OR another player rolls a natural 18/20, then they have been caught cheating and the beatings will commence.
