Sisyphus pushed one stone forever. You push each phrase until it stays.

Your stone is a phrase in the language you're learning.

You push it up by saying it from your own language, then by catching it by ear. A round takes a few minutes.

Some days you forget, and it slips back.

Everyone's does. Forgetting is part of the hill, and it isn't the end of the climb.

Rotea brings back what slipped, sooner.

A phrase you missed comes back in the next rounds. One you know waits longer, so your minutes go where they count.

Each time, it rolls back less.

The gaps between rounds grow from days to weeks, and the phrase stays with you longer each time.

“One must imagine Sisyphus happy.”

At the top, the phrase stays. Take the next one.
