Memory
Build a card-matching game from your own pictures, and give a leaderboard prize to the quickest players.
A Memory game lays out face-down cards. Players turn them over two at a time to find the pairs, and the best-ranked players win. Studio lists it as Memory Game. Here, Lindenhall's Garden Pairs has bees, butterflies, ladybirds and tulips, and the three best players win a picnic hamper.

Before you begin
- A campaign open in Build: see Your first campaign.
- A Performance Based Reward for the winners: see Leaderboard rewards.
- Your images:

It fills the screen from the top centre, with the title, the game and the button on top, and phones crop about a fifth off each side: keep text and faces in the middle.

If publishing is blocked
- No background image, or no thumbnail while the landing page is on: choose them on the Appearance tab.
- No memory items, an item without a picture, or cards that don't share one model: build the cards again, steps 8 to 16.

- An older Memory game that Studio no longer supports: build its cards again.
With no reward under Performance Rewards, the game still publishes, but nobody can win: Studio warns about it.
