You pick a game, then pick what character is winning the magic item random table roll if you succeed at said game. If you win, that character gets to roll for treasure and is forfeit from all other games. Then pick a game you havent played, and a character who hasn't won anything and carry on. If you do not win anything at a specific game, you can move on to the next game with the same character or pick a different character, that has not won anything. If you win at three games, get a perfect on any game or do not win anything at any game, you get to coin toss if you wish. 

You get to throw three knives of your choice at the target board. For each knife stuck in the board you roll progressively higher on the weapon or armor tables. If a knife hits a target it counts as double. If the knife hits bullseye you can coin flip. (6 points possible.) 

12 Cards are laid out. There are 6 pairs. You have three chances to find a pair. For each pair you find you get two points which allow you to roll progressively higher on the wondrous item charts. If you get three pairs, you can coin flip!

Open a box for 6 seconds. (1 round!) Then you take a test according to what you saw. For each answer you get correct, you can roll progressively higher on the random magic item charts. If you get all the answers correct you can coin flip! 

You randomly pull a card from Chicken or Hot Dog Game (TM). You have 1d4+1 chances to pull it off! If you succeed you get the points from the card. If you succeed and have any chances left, pull another card for bonus points! If you win points for each chance you have, you can coin toss. Those points allow you to roll on progressively higher random magic item tables. 

Heads your character is destroyed, make another character that cannot be the same species, class or background as the destroyed character. Tails, you get an Artifact."
