About 集中!ハムドミノ

While your smartphone is face down, the hamster will arrange the dominoes one by one.
When the time is up, give the first domino a "poke!" and the dominoes will fall all at once.

Concentrate with the hamster and get the task done.

■ How to Use
1. Choose a concentration time (15 minutes, 25 minutes, 60 minutes, 90 minutes)
2. Place your smartphone face down and start.
3. While your smartphone is face down, the hamster will arrange the dominoes (332 dominoes in 25 minutes).
4. When the time is up, give it a "poke!" to knock down the dominoes.

If you lift your smartphone midway through, the dominoes will wobble... Put it face down again immediately and you're safe. If you don't put it back, the dominoes will collapse.
