🧱 Stack at work
Every office has a colleague who claims elite reflexes because they once caught a falling mug. Stack is the 40-second audit of that claim. It fits inside a coffee break with room to spare, installs nothing IT would frown at, and produces the one thing office arguments never have: numbers.
Engineered for the gaps in a workday
A duel runs 30–40 seconds — the length of a microwave lunch cycle or a "call is starting soon" screen. No install, no account, no notification spam afterwards: open tab, settle score, close tab, deniability intact. The challenge link is asynchronous, so your 10:15 coffee and their 15:40 slump can still be the same duel.
The office championship
Drop one link in the team chat and let the results accumulate — every reply is a colleague's precision under pressure on the record. Run it as a Friday ritual, a sprint-retro tiebreaker, or the official decider of who books the meeting rooms. Escalation paths: games with coworkers and 1v1 games to settle arguments. For the record, post-lunch reaction times are measurably worse — schedule your title defence accordingly.
How to play Stack
- A block slides side to side above a fixed base.
- Tap to drop it. One drop — no undo, no second run.
- Your score is the overlap: how much of your block landed on the base.
- Better alignment than your opponent takes the round.
