OK Play (Cinco Linko in some territories) is a tile-placing strategy game where you compete to get five in a row. You take turns to place tiles next to each other in a growing grid. It is like Noughts and Crosses or Connect 4, but with an ever-expanding arena of play and with the ability to move already placed tiles, making for even sneakier play.

You start by taking one of the four sets of 15 plastic tiles and placing your first on the table. Players take turns placing tiles next to any tiles already played. The aim is to get five tiles in a row, horizontally, vertically or diagonally. Once a player has played all their tiles, they take turns to move tiles already in play until someone wins.

As play develops, so the opportunities to win become greater but so do the opportunities to lose. It's interesting because of balancing attack versus defence. This becomes ever more complex as all tiles are played and reaches a crescendo in the moving tiles phase. You must stay alert to the corners and sometimes have to work with opponents to stop another player from winning, whilst still trying to place the winning tile yourself.
