2. Chairbucks:-
It is a simple game of skill , strategy ( use math ) & little luck
Objects used – A rotating chair and bucks (coins) or any alternate
item which has two faces and there is equal probability of both
the faces . Eg – Bottle lid , Eraser
Lets find out what it is !
3. How to play ?
•Every participant stands in a circle separated at equal distance . 4-8 can
play this game. Total value of game = total bucks collected . Each
participant contributes equal amount.
•Every person takes turns alternatively to rotate the chair. The one to whom
the chair is pointed is CHAIRMAN. The chair should complete two rotations
before it stops and points to a person. Otherwise its an invalid round.
•After each turn of chair , everyone tosses the coins in air. If its all heads or
all tails – CHAIRMAN is the winner of that round.. Otherwise continue.
•If there are less participants (<=4) – The winner of each round takes 1
buck of that round and game continues until all the bucks get exhausted.
Few of them get less bucks and few get more.
•If there are more participants (>4) – The one who gets all heads / tails is
the winner .There is only 1 round and the winner of the game.
•Chairman only gets a chance to win / take the bucks !

6. Eg – How to play when
there are 4 participants:-
Each participant rotates
the chair
Figure out the chairman
(where the chair stops )
Game
continues
until all bucks
Everyone tosses the coins are exhausted
Next person
rotates chair
and game
continues
All
Chairman wins
heads/tails Yes
round and takes 1
?
buck for the
round
No
7. Eg – How to play when
there are 8 participants:-
Each participant rotates
the chair
Figure out the chairman (
where chair stops )
Everyone tosses the coins Take all bucks
Continue and walk away !
till a winner is
found
All
heads/tails Yes Chairman wins
? game
No
8. Strategy & skill :- One can control force while rotating chair ( which is a skill )
so that chair points towards oneself ! This is an element of the game which
the participant can control a litle bit.
Luck factor:- Others rotating the chair and chair pointing towards you !!
Coins – Tossed coins being Heads / Tails – Less probability.
The game can be played in variants like team play where the participant shall
try to rotate the chair so that it stops and points towards its own team.
Rules can be modified and made complicated where the bucks to take varies
from probability ..
The more probable is the combination , the less can be the stake to take
away and vice versa !!!
Eg – Probability of all heads is 1/16 , probability of 3H,1T is ¼ ..
9. 4 participants –
Total of 4 coins collected , 1 from each participant.
Few of combinations of coins tossed –
HHHH
HHHT
HHTT
TTTT
Probability of chairman winning round if all heads / all tails
= 2/16 = 1/8
