Look at a position, then put it back from memory.

Position Recall

Position Recall trains your memory for where pieces stand. A position is shown for six seconds and then cleared. Put every piece back on its square from memory and press Check. A perfect answer brings a position with one piece more, starting from four. Your score is the largest position you rebuilt without a mistake.

How to play

  1. Press Start and study the position. The board is cleared after six seconds.
  2. Choose a piece from the tray and tap the square it stood on. Tap the same piece on its square again to take it off.
  3. Press Check. Right squares turn green, wrong and forgotten ones red. A perfect board earns a harder one; a mistake starts again at four pieces.

Questions

How do strong players remember positions?
They see groups, not single pieces: a castled king with its pawns, a pair of rooks on a file. Studies of chess memory have found that masters recall positions from real games far better than beginners do, and much less so when the pieces are placed at random.
Are these positions from real games?
No. The pieces are placed at random, which is harder to remember than a position from a game because there are no familiar groups to hold on to.
What counts as a mistake?
A piece on the wrong square, the wrong piece on a square, or a piece left off the board.
