The End Game Screen

The End Game screen is mostly self-explanatory. You can press Replay to play the level again, or press Exit to quit to the level select.

In Multiplayer, the End Game screen lists player names, teams names (if Team Mode is enabled), total score, a breakdown of gems collected, and marble skin used. Ratings are displayed if ratings are being calculated (otherwise it shows N/A), and how much a player won or lost.
On the right side of the screen, from top to bottom, the host of the match can:
Replay the level
Quit to Level Select
Quit to the Leaderboards chat
Save Spawns: Save the match's spawns as they appeared in the match.

Note: When playing Singleplayer levels online, you will be shown the rank for that particular level on the leaderboards based on time you reach.
