Tenzi Rules

1 Overview

TENZI is a fast-rolling dice game for 2 to 4 players (or more with extra sets) published by Carma Games. Each player gets 10 dice. On "Go," everyone rolls simultaneously and races to get all 10 dice showing the same number. First to shout "TENZI!" wins. Games last about 3 minutes.

TENZI is one of the most purely chaotic party games ever made. It requires no setup, no turns, no strategy -- just rapid rolling and fast hands. Perfect as a filler, an icebreaker, or the thing you play between heavier games.

2 Components

• 40 standard 6-sided dice in 4 colors (10 per player)

Extra TENZI sets can expand play to 6 to 8 players. The dice are standard d6s, so you can also play with any dice you have on hand.

3 Setup

Each player takes 10 dice of their color. Players sit close enough that they can see each other's dice. No board needed -- just table space for rolling.

4 Classic TENZI

1. On "Go," all players roll all 10 of their dice simultaneously.
2. Look at your dice and decide which number you are going for (typically whichever number shows the most faces).
3. Set aside all dice showing your chosen number. Re-roll the rest.
4. Repeat -- keep setting aside matching dice and re-rolling the others -- as fast as you can. There are no turns; everyone rolls at the same time continuously.
5. The first player to get all 10 dice showing the same number shouts "TENZI!" and wins the round.

You are not locked into your initial number choice. If you have three 4s and then roll four 6s on your next roll, you can switch to 6s. However, switching too often costs time -- staying committed to one number is usually faster.

5 Winning

First to shout "TENZI!" with all 10 dice showing the same face wins the round. Most groups play a set number of rounds (first to 5 wins, or best of 10) rather than a single round, since each round is over in under a minute.

6 Popular TENZI Variants

The official TENZI Dice Party Card Set includes 77 variant games. Here are the most popular:

7 Tips

• Pick your number immediately after the first roll. Hesitating costs precious seconds. Go with the number that shows the most faces on that first roll.
• Re-roll non-matching dice in one smooth motion. Cup them in your hand and roll all at once rather than picking them up one by one.
• Don't switch numbers unless you have 4 or fewer of your current number. The math rarely favors switching when you already have 5+ dice committed.
• Watch opponents briefly on the second roll. If someone is clearly on 6s and you have equal 6s and 3s, choosing 3s avoids the competition for what feels like the luckiest number in the room.

8 FAQ

9 Strategy & Speed Tips

Choose Your Number After the First Roll

After your very first roll, immediately identify the face value that appears most often among your 10 dice. Lock those dice (set them aside) and roll only the remaining dice. Do not overthink this — your brain can identify the modal value in under a second. If you have three 4s and two 6s, keep the 4s without hesitation.

The Lock-and-Reduce Method

Set aside matched dice and physically reduce the group you are rolling. Practicing the fluid motion of scooping only non-matched dice, rolling them in one smooth motion, and setting new matches aside is a trainable physical skill. Fumbling with dice wastes more time than suboptimal number selection. Speed is as much about physical coordination as dice luck.

Know When to Switch Numbers

If you are 5+ rolls in and have only 2 or 3 dice matched, seriously consider switching to a different face value if you just rolled four of a new face. The pivot threshold: if you have locked 3 or fewer dice after 6 rolls, switching to any face showing 4+ on your current roll is usually worth it mathematically.

Controlled Urgency

Tenzi is played simultaneously — watching a competitor near completion creates psychological pressure. Keep your eyes on your own dice. Rushed, panicked rolling scatters dice unpredictably and slows you down. Steady, controlled throws that land cleanly on the table surface are faster than wild slams that send dice flying.

10 Probability & Math

Understanding the probability of Tenzi helps make smarter number-switching decisions in real time:

• First roll expected matching dice: With 10 dice, the expected number matching your best face after one roll is approximately 1.7. But the distribution has variance — there is roughly a 50% chance you roll at least 2 of your best number on the opening throw.
• Probability of winning in one roll: (1/6)^9 ≈ 0.00000033% — essentially impossible. Tenzi always requires multiple rolls.
• Expected rolls to completion with optimal strategy: Approximately 14 to 20 total rolls. Players who switch numbers at the right time finish faster on average than those who rigidly stick to an early choice.
• The convergence acceleration: Progress accelerates dramatically as you lock more dice. With 7 locked and 3 remaining, each roll has roughly a 0.46% chance of finishing in one throw. Expected additional rolls to finish from this point: about 6. The last 2–3 dice are where races are won and lost.
• All face values are equal: No face value is statistically better to chase than any other. The only decision that matters is always choosing the face with the most dice showing after your current roll.
