7️⃣ Buzz: The Seven Game

🕹️ How to play

1. How to start a buzz game run: Pick the rule (default: numbers containing a 7 OR multiples of 7; you can also choose digit-7 only or multiples only) and the speed tier (relaxed, standard or extreme). Tap start, wait out the 3-2-1 countdown, and the first number appears the same moment the timer begins.
2. How to call each number: One number fills the card. If it has no 7 and is not divisible by 7, tap SAY IT on the left. If it is a seven, you must tap PASS on the right. Every correct call jumps to the next number and resets the ring — a little shorter each time.
3. What happens when you get one wrong: A wrong tap or an expired ring ends the run instantly. The verdict tells you exactly what went wrong (for example, 27 contains a 7, so it had to be passed) and the scorecard shows how many numbers you passed, where you stopped, your average reaction time and your rating.
4. How to play with friends on one phone: Switch the mode to pass-the-phone, add 2 to 12 names, and everyone plays one run with the same rule, speed and starting number. When the last player is done the leaderboard ranks by numbers passed, breaks ties by average reaction, and draws a penalty for last place.

📖 Rules & variants

Core rules: players count 1, 2, 3 out loud and must never say a 'seven' number — they say buzz (or pass) instead. This online version turns that into a two-button judgement: the app deals the numbers, you tap PASS or SAY IT, and every call is judged by the machine, so nobody argues about who slipped.

The three rule variants: the classic default treats both numbers containing the digit 7 (7, 17, 27, 70–79…) and multiples of 7 (14, 21, 28, 35…) as buzz numbers. House variants that count only the digit or only the multiples are one tap away, and the tutorial cards re-judge themselves the moment you switch, so the difference is visible rather than described.

Buzz numbers from 1 to 100 (default rule): 7, 14, 17, 21, 27, 28, 35, 37, 42, 47, 49, 56, 57, 63, 67, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 84, 87, 91, 97 and 98 — thirty numbers in total. The whole 70s decade is a buzz, which is where most live games fall apart.

Timing and scoring: every number gets its own countdown. Standard starts at 3 seconds and loses 30ms per number down to a 1.2s floor; relaxed runs 4s down to 2s and extreme 2s down to 0.7s. A wrong tap or an expired timer ends the run. The score is the number of calls you passed; the number you stopped on is shown for context only, and 999 straight is a clear.

Records and the four runs that never count: best scores are kept per rule × speed (nine buckets) in your browser only, never uploaded. Contest runs, random-start runs, practice runs and runs interrupted by leaving the tab are not recorded — a yellow note says so before you start, never after you finish.

House variants: a random start (a number drawn between 2 and 20) stops veterans from memorising the sequence. Table rules such as reversing direction after a buzz, or double-buzzing on 77, stay verbal — the app only judges the number in front of you. Some groups also let the loser start the next round; house rules differ, so play it your way.
