iOS Contest, Round 2: Submissions
We received 9 submissions for the Second Round of the iOS contest (watchOS).
Some of them used TDLib and because of this can currently only run on emulators, not on real Apple Watches. We decided to upgrade TDLib to make them work on actual devices before we evaluate the submissions.
Naturally, we will take into account the effort that was required to make the apps work without TDLib and these tweaks on our side when assigning awards. Stay tuned! π

Submissions for the GIF Π‘ontest are open until March 31, 23:59 (Dubai time).
We suggest that you try submitting at least some of your reaction videos early β to make sure you've familiarized yourself with the process. Videos submitted late will not be accepted for the contest.
Instructions:
https://contest.com/docs/gif-contest-submission
If you have any questions, please check the FAQ.
A few extra tips, in case you're having any issues:
1. Prepare your videos for publication in an external video editor (it is not recommended to use the built-in Telegram media editor for this purpose).
- Aspect ratio: between 1:1 and 4:3
- No audio track! (especially important for uploading via desktop apps)
- Suggested width: 380, 640 or 848
- Suggested height: a multiple of 16 (but remember to use the correct aspect ratio!)
(Other widths/heights may also work β but if you run into problems, try the suggested ones.)
2. Once you've prepared your videos for publication, use an official app to send them to your channel.
- Send as a video (not file).
- If you use a mobile app, set the maximum quality.
- If you use iOS, disable audio before sending (tap on the speaker icon) β even if you removed the soundtrack when preparing the video for publication.
- If you use Android, don't disable audio β instead remove the soundtrack when preparing video for publication.
3. If @ContestBot tells you your videos were not accepted, you can tap the "Show videos with issues" button to get details on each problematic video.
4. If the bot tells you you haven't submitted any videos, see number 1 in this messageπ.
Good luck! And don't wait until the last moment. π

If you are trying to submit videos to the GIF Contest, but no watermark appears and @ContestBot doesnβt recognize them, make sure that you have disabled the soundtrack completely before uploading. Your video file must have no audio channels for Telegram Desktop to recognize it as a βGIFβ (and for the bot to accept it).
There are many ways of disabling the audio track in a video. If youβre having difficulties, we suggest googling for a solution that works best for you.

Aptitude Test Contest: Results
The results of the Aptitude Test Contest are here!
This contest was one of the most involved, requiring that participants pass our evaluation tests to take part, and then demanding their constant attention for over 1.5 months.
We have split the entire remaining β¬250,000 Quiz Contest prize pool among those participants who completed all the tasks:
Participants had to design a set of 30-question Quizzes which tested three aptitude groups:
β’ English Language
β’ Mathematical Ability
β’ Spatial & Logical Thinking
They then reviewed 9 Quizzes from other participants (that's 270 questions) and submitted rebuttals β reflecting on the reviews their work received.
Finally, Telegram Judges analyzed the content of each Quiz, its adherence to the rules and its overall usefulness. The quality of Peer Reviews and the validity of Rebuttals was also assessed.
All of these ratings produced a final Contest Score for each Quiz, between 1 and 4.3.
There are 4 reward tiers for this contest, per Quiz:
π₯ β β¬3000 β Contest Score 4+
π₯ β β¬1500 β Contest Score 3+
π₯ β β¬500 β Contest Score 2.1+
π β β¬50 β Contest Score 2 and below
Bonuses were awarded for Outstanding Peer Reviews.
Penalties were incurred for Unoriginal Content and Low-effort Peer Reviews.
