You can use all DOOH spots as fill-up spots, except spots with live tags ### How filling up with ads it works The playback frequency of DOOH spots determines which spot is selected as a fill-up spot under the following conditions: - **Running spot**: A currently running spot cannot be used as a fill-up spot. The same spot, including fill-up spots, should not be played twice in a row. - **No repetition**: If a DOOH spot is scheduled to play next but was previously used as a fill-up spot, it will not play again immediately. Instead, it will play in the next cycle, if applicable. - **Random SSP**: If there's unused DOOH airtime, the player can also [randomly play SSP spots to fill the time](/grassfish/docs/fill-up-with-ssp-spots). ## Fill up with DOOH spots To set the DOOH fill-up, perform the following steps: 1. In IXM One, go to the player configuration or the configuration group: - For an individual player, go to **Channels > Location**.
