Neighbour memory

How to play

1. Tap a card to flip it, then tap a second one.
2. If the two portraits match, they stay face up. If not, they flip back, so remember where each one was.
3. Find every pair using as few moves as you can. Time only breaks ties.
4. Choose a level: Easy has 6 pairs, Normal 8, Hard 12. Each level has its own board.
