Today's Daily has one free first attempt. Eligible registration and friend-referral actions can earn up to 2 extra attempts per UTC day, for a maximum of 3 total starts including the free Daily.

Find a drive worth revisiting
Each published challenge has its own source record, starting conditions, scoring objective and simulation version. Browse by the available teams, dates or situations, then open a challenge to see those details.
The archive contains published challenges. Unreleased dates and unverified historical situations do not appear as playable entries.
History is a starting point
A challenge may begin at a real game's recorded state. After you take over, its simulated plays can diverge from what happened. An archive attempt does not replace your first Daily result.
Use the challenge revision to identify the starting state used by an attempt. See updates and data sources for how to check a record or report a problem.
