Pairs
A memory game where every column is a position and every cell is a card.
The table is the board. There is no list here at all. A column is a position, a row is a row of cards, and the grid falls out of the same widget.
Animating a card from its own cell
Each card animates itself in Sequencer. The table hands it a row and a column, and the cell runs the flip, the match and the miss.
Cells get reused, so the card you just flipped can come back as a different card. The table stops a released cell's animations and resets its opacity and transform, and On Cell Assigned puts the face and the back of the new card in place.
How it's wired
The model deals a shuffled deck of pairs across any board with an even number of cards, up to 16 pairs. The cells take the clicks, and with selection off no row marks itself.
