Wannabe Board Game Designer

Preliminary dates
Earliest Date for Games to be Publicly Available: January 1st, 2026
Submissions: June 1st to September 1st, 2026
Development: Until October 15th, 2026
Typo Corrections: Until before October 20th, 2026
Freeze (Changes Locked) / Voting: October 15th to November 15th, 2026

Games must have rules and components before September 1st, but they can still be changed and altered, even significant changes (although the more radical the changes, the more confusion there will be in players/voters; try to keep the spirit of the game).
Every game still in the contest will be considered “frozen” on October 15th – no need to update the status.
