Write the challenge before sharing
Choose a single title and a measure visible in its game. For Coin Drop, use the points shown after each run; agree whether the group counts the best attempt or total points from a fixed number of attempts. Add a start and end time with a timezone if friends are spread across regions. A shared link lets everyone reach the same title.
Keep results easy to verify
Ask each person to report the same kind of result and, if helpful, include a screenshot of the game’s end state. Do not request private account details or treat a screenshot as proof of skill; it is just a convenient record. If the game changes during the challenge, pause and agree whether everyone restarts with the same conditions.
Close the round fairly
At the deadline, list every valid attempt using the agreed rule. Share a tie or run one short tie-break round with one attempt per tied player. Then choose whether the winner picks the next title or everyone votes. A finite round is easier to maintain than an open-ended request to “play sometime,” especially when participants check messages at different hours.
Questions about asynchronous games with friends
Does async mean the game saves everyone’s turn?
No. The challenge is coordinated through shared instructions and reported results; participants play independent runs. Do not assume an unfinished run is stored automatically.
What makes a score challenge fair?
Use the same title, attempt count, time window and result rule for everyone. State how ties and changed game conditions will be handled before play begins.
