Aliens have shuffled the space cards. Find all the pairs.

What you learn

Remembering a state helps solve a game.

Edit your program and press Run. Gold highlights the running instruction. Pause, Step and Undo step help you understand. There is no time limit.

Example program

pairs(4);
goal(8);

onMatch {
  if (isMatch) {
    addScore(2);
    repeat(2) { sparkle(); }
    say("goodjob");
  } else {
    addScore(0);
    wobble();
    say("tryagain");
  }
}

Make it your own

Change repeat to run the instructions inside { } several times. In tap, memory and quiz games, if checks a choice; else runs when the condition is false. In pixel art, color chooses a color and paint fills one square; movement commands change the pen position. Shows use pose, say and beat to change actors, speech and notes.
