Working memory is the ability to hold something in your head and use it a moment later. Keeping a shopping list in mind. Taking notes while the teacher is still talking. Doing sums without paper. It quietly sits underneath almost everything we get done in a day. Working Memory Lab trains that ability with nine mini games. One to two minutes a round, for kids and grown-ups alike. NINE MINI GAMES - Reverse Recall — colours appear one by one; tap them back in reverse. Rearranging in your head. - Match Back — tap when a picture matches the one a few steps back. Taking in the new while letting go of the old (an n-back task). - Cup Shuffle — follow the swapping cups and find the ball. - Dual Task — solve a sum, then memorise a picture, over and over. The real thing: holding on while busy. - Copy the Order — tap the animals in the order they appeared. - Take the Order — remember what each table ordered. Some come alone, some as a family. - Number Flash — numbers flash by; add them all up in your head. - Math Relay — "plus 3", "times 2" — keep the running total going. - Grid Memory — remember which squares lit up, wait while the board goes dark, then tap them. BUILT TO KEEP YOU COMING BACK - Six levels, from Easy to Legend - Score grows with speed and with answers in a row - 24 badges and six ranks to climb - A daily play streak - Memory span — see, as a number, how much you can reliably hold - The app spots your weakest game and suggests practice SAFE FOR CHILDREN - No account.
