Rules: 1. Any type of paper can be used. 2. Participants are allowed to paint and glue models if it would not prevent identification of all elements of the model (including pre-creased lines defining the assembly process). This rule does not apply to the participant’s own design.

3. Only photos never published before the olympiad are allowed. 4. Each model should be photographed from at least three angles

to clearly display all the details. Low quality photos will not be considered. Recommended size of pictures is from 640x640 to 1500x1500 pixels.

5. Minimal editing of the pictures is allowed as long as it doesn't affect the appearance of the model. E.g. you can crop photos, reduce the noise, change color balance but you must not add, erase or change any details.

6. Upload the photos to your profile before the deadline (November 6). Сheck the timer in your profile.

7. The winners of the first round are determined based on the number and quality of completed tasks. Check your profile for the further instuctions.
