3D Selection Game
Players pick one of several 3D objects, and an animation inside the model shows whether they've won.
A 3D Selection Game lines up identical 3D objects, and players tap the one they think hides a prize. An animation in the model plays the result. Here, Lindenhall's Pick a Pot shows three flowerpots: if a daisy grows, the player wins a seed kit.

Before you begin
- A campaign open in Build: see Your first campaign.
- A Luck Based Reward for each prize: see Create a reward.
- Your 3D model, with one animation for a win and one for a loss, and your images. Here, the flowerpot has WIN (a daisy grows) and LOSE (the pot wobbles).

The other two modes
Scheduled Rewards releases the prizes at moments spread between two dates, whatever the odds. Set its Type, Start Date and End Date under Rewards distribution. Those dates only decide when prizes are won: the Dates tab decides when the game is open.

Lottery enters every player in a draw instead: nobody picks an object, the Lottery Animation plays, and the winners are drawn later. Write the Lottery Participation Message, choose the animation, and link a lottery made for this game: see Lottery rewards.
