Q: How do I earn OWL 2021 T-Mobile Perks?
A: You can earn OWL 2021 T-Mobile Perks by linking your battle net account to your YouTube (Google) account and watching OWL 2021 matches (including rebroadcast encore matches.)
Q: What are the OWL 2021 T-Mobile Perks?
A: During non-tournament weekends (regular season qualifier matches that take up 3/4 weeks of play per monthly tournament), 5 OWL Tokens can be earned per hour.
Durning tournament weekends (at the end of the 3 weeks of qualifier matches), the community will be asked to voice their opinions on which OWL Gray/White skin should be available to earn alongside the regular tokens. It is not confirmed, but a possible 4 hours watched on tournament weekends should suffice.
Additionally, special edition community designed sprays will be available throughout OWL 2021, with some being based off of the teams winning the 4 monthly tournaments. There will be an opening weekend spray that is designed by our own Soe Gschwind. This is confirmed to take 4 hours of watchtime on the opening weekend to earn.
Q: Can I earn OWL 2021 T-Mobile Perks on my PS5/Xbox/TV’s etc. respective apps?
A: Whilst some have had success earning OWL 2021 T-Mobile Perks on anywhere other than YouTube(.)com, the YouTube mobile app or the OWL app, it is advised that - to get maximum value - you watch on the aforementioned standard platforms.
Q: If I can’t earn OWL 2021 T-Mobile Perks from watching the streams because of my location, how can I get Overwatch League Tokens?
A: For those who reside in a country not eligible to earn tokens from watching online (check which countries are not eligible at the OWL website) you can purchase Overwatch League tokens on the gaming platform that you play Overwatch on. Furthermore, OWL Gray/White skins are not available for purchase at this time.
Q: I am having trouble earning tokens, skins, or sprays. Can Blizzard help me get the tokens that I missed?
A: Blizzard Customer Support is unable to see or troubleshoot Overwatch League Token drops.
Q: When I am watching, how do I know that I am definitely earning OWL 2021 T-Mobile Perks?
A: ‘Connected’ text and symbol (similar to a diamond) will show alongside a tick.
Q: When will I receive my OWL 2021 T-Mobile Perks?
