About Kobadoo Numbers

This is the memory drill with the hardest material in it. Two-digit numbers have no shape and no colour to hang on to, so there is nothing to recall except the numbers themselves, in the order they came.

Levels grow by adding a number rather than by shortening the look, which keeps it fair as it gets long. It is a working memory exercise wearing very little disguise, and it is honest about that. It plays in either orientation and needs one tap per answer.

How to play

  1. Watch the numbers appear, one after another.
  2. Tap them back in the same order once they hide.
  3. Each level adds another number to hold.

Tips

  • Say them out loud as they appear. Sound is stored apart from sight, so you end up with two copies of the run.
  • Read 47 as forty seven, not as four then seven. One word takes up less room than two digits.
