What is in the daily set?

Ten questions, the same worldwide for that UTC date. The first five are 13-tile one-suit tenpai: select every wait. The last five are 14-tile discards: cut the tile that leaves the most winning tiles.

When does the set change?

It changes on the UTC calendar day. The time on the page is about when that happens on your local clock, not midnight in your time zone.

How do the leaderboard and share work?

The first signed-in submit of the day is the one that ranks, and later submits keep that correct count and time. Order is more correct, then less time, then earlier submit, and the list shows 20. Share sends this page and your correct count, not a challenge link for one hand.

Why is there no countdown?

This set does not use the timed or practice switch from the other drills. Total time is the clock from the first question until the tenth is done, including feedback. After you finish, a refresh returns you to today’s result.

What this drill trains

Daily Challenge is five tenpai hands, then five discards, the same worldwide for the UTC date. Tenpai is 13 tiles and every wait. Discard is 14 tiles and one cut, both at Simple. There is no per-question clock. Total time includes the feedback between hands.

How to practice

Answer in order. Tenpai needs every wait. Discard wants the most winning tiles left, and ties count.
Submit, then continue with Enter or Space. A miss does not end the set. The result shows correct, wrong, and total time.
Signed-out results stay on this device. The first signed-in submit of the day joins the board and your streak. Later submits do not replace it.

How to read the result

Share sends this page and your correct count, not one hand. The board ranks more correct, then less time, then earlier, and shows 20 names. Rules are in Daily Challenge
