Hide and seek is a form of solitaire played with 52 cards. 13 packets of 4 cards are placed face down. The packet on the left is the ace packet, the one next to it is the king packet and so on, all the way to the right to the two-card packet.

The top card of the left packet is turned over and placed face up under its corresponding pile, i.e. a 7 is pushed under the pile of 7s. Next, turn over the top card of the pack under which you have just slid a card and slide it under its corresponding pile. Proceed in this way with all the cards in turn. When all the packets have been allocated, the solitaire has been completed. From left to right, there must now be 4 aces, 4 kings etc. up to 4 twos.
