Date Stamp.
Five moments in history, one tape of years. Flick the tape until the needle finds your year, press the stamp, and the ledger counts every year you missed by. Lower is better.
Date Stamp is a trivia game built for the short window between meetings. The round is self-paced, with 1 attempt before the score locks. What you know, what you almost know. The team-wide leaderboard rebuilds itself daily, so the only thing carrying from yesterday is bragging rights.
- 01GoalFive moments in history to place on a tape of years, easy to brutal. Your score is the total years your five stamps miss by, so lower is better.
- 02StampingA gold needle sits fixed over the tape. Drag or flick the tape until the year you believe sits under the needle, then press the stamp.
- 03Fine controlFast flicks cross centuries and slow drags move a single year. On a keyboard the arrow keys nudge one year, ten with shift, and Enter stamps.
- 04The perfect stampLand within a year of the truth and the stamp costs you nothing.
