Tournament mode
For organized events: pick bracket style, match length, clocks, and house rules up front.

Tournament checklist
For organized events or multi-round knockouts.
- Bracket formats: single elimination or round-robin scheduling.
- Each match is often first to two game wins (Bo3) or three (Bo5) to advance — confirm before the bracket starts.
- Suggest 15–30 seconds per turn with a draw penalty if time expires (house rule).
- Before play, agree whether stacking +2/+4 chains is allowed to avoid mid-match arguments.
Stacking note (house rule): when allowed, a +2 can be answered with another +2 to push the stacked draw onward until someone cannot continue and must take the full pile. Official UNO rules do not endorse stacking.

Publish the clock: Put turn limits and pause rules on a sheet everyone signs — it prevents mid-bracket debates.
- check_circle
Stacking in writing: If stacking is allowed, define whether +4 can answer +2 and what happens on illegal plays.
