The daily challenge is osu!lazer's own daily event, and it works the same way on somtum.fun. Every day a new map opens in a playlist room in TumThai: play it as often as you like, and your best score counts. Open it from the main menu: Play → Daily challenge.
The daily challenge is TumThai (osu!lazer) only: osu!(stable) has no daily challenge.
Every map is picked automatically from ranked maps that haven't been a daily challenge before. Each one is 1 to 5 minutes long. Like on osu!, the week starts easy and gets harder:
| Day | Star rating |
|---|---|
| Thursday | 3 to 3.5★ |
| Friday | 3.5 to 4★ |
| Saturday | 4 to 4.5★ |
| Sunday | 4.5 to 5★ |
| Monday | 5 to 5.5★ |
| Tuesday | 5.5 to 6★ |
| Wednesday | 6 to 6.5★ |
The challenges are in osu! mode for now.
You can add these mods to your plays, but nothing that changes the speed (no Double Time, Half Time and the like):
| Mode | Allowed mods |
|---|---|
| osu!, osu!taiko, osu!catch | Easy, No Fail, Hidden, Hard Rock, Sudden Death, Perfect, Flashlight |
| osu!mania | Easy, No Fail, Hidden, Fade In, Sudden Death, Perfect, Flashlight, Mirror |
somtum.fun also has a map of the day on Discord. They're two different things:
| Daily challenge | Map of the day | |
|---|---|---|
| Where | A room in TumThai | Any normal play on the map, in TumThai or osu!(stable) |
| Map | Ranked, 1–5 minutes, harder each day of the week | Random ranked map, 3–6.5★, 1–7 minutes |
| Mods | Only the ones above | Any (except Relax and Autopilot) |
| Who wins | Best total score in the room | Best pass that day by pp, then score |
| Reward | Streaks, percentile and the daily challenge ranking | The Map of the Day Discord role for a week |
