What it is

A sunny beach game. Place your pink shells on the sand while the other side places orange starfish. Three in a row wins on the little tide pool; on bigger beaches you need four or five, and sandcastles get in the way. Play Pip, Bramble, Olly and Sage (who never makes a mistake on the little board, so a draw is a great result), solve fork puzzles, or play a friend.

What children learn

For fun: blocking, making forks (two threats at once) and seeing why perfect play ends in a draw. PlayTime games keep stars but are not counted as learning evidence.

What it teaches

  • Turn-based strategy

How to play

Tap an empty square of sand to place a shell. Keyboard: arrow keys move around the beach, Enter or Space places. Easy levels mark the open squares and let you take a move back.

Plays with: Touch Mouse Keyboard
