Until today, racing in the Arena meant catching another player online at the same moment. Now you can queue any time.
If nobody else is queued, the open seats fill with recorded runs from real players, clearly labelled as replays, on the same deal you're playing. Live players are always seated first, and you can choose to wait for a live opponent instead.
Also in 1.4.39: a "How to play" card for anyone new to FreeCell, and arrows on the Daily Challenge win screen to step back through past days.
See you in the Arena.
