+# Accuracy
+
+Accuracy defines how accurately a player is hitting [hit objects](/wiki/Hit_Objects) on a [beatmap](/wiki/Beatmaps). This value varies from 0 to 100%. Accuracy can be seen in the top-right corner while watching a replay or playing a beatmap.

+# Drain time
+
+Drain time refers to the total duration of a [beatmap](/wiki/Beatmaps) that requires the player to be active. Drain time does not include breaks and unmapped portions of a beatmap.
+
+Beatmaps with very long drain times (usually longer than 5 minutes) are typically referred to as marathon maps and require endurance beyond the norm in order to complete successfully.

+# Spectate
+
+Spectate, or *spec*, is when someone watches another player playing a [beatmap](/wiki/Beatmaps) in real time (with approx. 500ms delay). To spectate, open the extended chat and click on a grey user panel.
+
+For this to work, you will need to have a copy of the exact same beatmap the player you wish to spectate is playing. However, if you have an [osu!supporter](/wiki/osu!supporter) tag, the beatmapset will be downloaded and processed for you through osu!direct.
