The course of a challenge is as follows:

Start

• The founder of a group challenge creates a goal and starts the challenge.
• The duration of the challenge is the overall duration of the goal, even if some days are excluded (a day off) from the goal. See: A day off.
• A person can participate (accept) the challenge whenever they want.

Taking part in a challenge

• Accepting a challenge the predefined goal by the founder will be created for you.
• The first day, after accepting the challenge, is only counted if it's a "SUCCESSFUL" day.

The winner

• The person with the most "SUCCESSFUL" days checked wins.
• If two persons have an equal amount of "SUCCESSFUL" days, the person who has checked the most "KINDOF" days wins.

Calculation (statistics)

• "SUCCESSFUL" days are counted even from the excluded days.
• "KINDOF" days are counted to streaks.
• Failed and unchecked days are counted as failures if the day is active in the challenge goal.

Notes

• Progress is tracked exactly the same way as tracking any other goal in Habinator.
• You can adjust the goal to your needs! Only the duration cannot be changed.

The idea of a challenge is to make progress together, but most importantly to have fun!
