This game is similar to «karuta» (an educational way of using cards popular in Japan).
In this game, spread numbered AGO cards (i.e. the phonics cards) face up on a table.
One player takes the role of leader. They select a card on the table, and read it out, line by line (or even slowly selecting words to read one by one, in any order). The do not touch the card, or indicate its location. The other players then race to locate this card. The first player to touch it, wins the card, adding it to their score pile.
Players only get one chance to guess the card. The first player to guess right takes the role of leader, calling out the next card. If all players guess wrong (which shouldn’t really happen), the leader wins the card and gets to call another.
Most cards at the end, wins.
