How to play
Objects are laid on the board. Look carefully: they disappear, then come back with one change. An object may have appeared, disappeared or been replaced: tap its place, even if empty. One more object each round; a mistake costs 2 seconds. Fastest wins.
Tips to get better
- Remember the empty places as well as the objects: that is where one can appear.
- Group objects by row ("apple, key, rocket…"): a list is easier to remember than a picture.
- A replaced object sits where the old one was: compare places first, then objects.
What this game trains
- Working memory: keep a few items in mind and recall them.
- Attention and focus: quickly pick out the right item among distractors.
