w3_jam jury members about the event

Michal Dabrowski, Elympics

We can call the first edition of w3_jam a success. Teams from around the world showed us diverse approaches to web3 gaming, and although it was their first experience with play-to-earn development, all of them managed to build playable games. Congrats!

Jaroslaw Kruc, G2A

Elympics managed to gather interesting and experienced specialists, both among participants and jury members. The optional workshops presented various blockchain topics in an easily-digestible way. The event theme was universal but allowed participants to show us their skills and add something personal to their projects. It was a very good experience.

Tomasz Kowalczyk, StarTerra

Participating in Elympics’ gamejam as a jury member was a great pleasure. Its organization and the professional approach of the team distinguishes it among other web3 events across the world.

Dominik Kowalewski, PlayNity
