In the Indian subcontinent, it is sometimes spelled Coat Peace, Kot Pees, Chokri, Chakri, Rung or Rang.
Alternative names include Seven Hands (Iran), t'rup Chaal, and Hok (Israel).
In the Dutch-speaking world, a similar game (and likely derivative) is known as Troefcall (Suriname and the Netherlands).
The game is played with a full standard deck of 52 cards by four players in fixed partnerships, sitting crosswise.
But this can't be changed by the person who announced trump or their partner The player who sits after the dealer in the direction of play (which is typically counter-clockwise) is known as trump-caller.
Player have to call first for Continuing afterwards and winning all tricks is a rare achievement known as a bavney or baunie.
There is a variation played only in North India, specially Delhi, where the only way one team member can communicate with the other, is by tapping the table (or any surface) called a 'thaap' intended to indicate to the team member to repeat the colour just played.
The person showing his trumps should have the greatest card of Rang to win the trick.
Basic rules of the Rang are applied to this game as well, i.e., 52 cards deck, four players in fixed partnership, etc.
The cards are dealt in batches of 5-4-4, the trump-caller announces the Rang (trump suit) and starts the game with first trick.
If any of the player does not have the suit of the trick, he can play card from trump-suit (rang), often referred to as kaat lagana (Urdu: کاٹ لگانا).
It is a variant of Single Sar in which tricks are not automatically collected by their winner's party.
In this game a kot is defined as collecting all tricks by trump-caller team, which unlike bavney in standard court piece is realistically achievable.
A grand-kot or goon-kot is defined as collection of all tricks (sars, (Urdu: سریں )) by the dealing team.
Winning seven hands in a row by collecting the majority of tricks is sometimes equivalent to a kot.
Some players like to allow the rule of using two aces at same time to get the declared number of "Sars".
In this format, the dealer distributes all 52 cards without the trump being called and the game begins.
During game whoever runs out from a specific suit will make trump by throwing colour card.
After the trump is made, any player has to make double sar in order to win tricks.
Satat, the most popular game of Mauritius, differs from court piece only in the special role assigned to the 2 of hearts and the existence of a system of signals for the exchange of information between partners.
However, the 2 of hearts need not be passed, and neither of the players who won the kot may use this opportunity to rid themselves entirely of a plain suit.
[6] Trup kasiet is a satat variant in which the trump-caller makes trumps secretly by putting a card face down.
Since kot and bavney are more common in this variant, no cards are passed in the following hand.
[6] Dehla pakad is double sar with the further variation that tens are counted instead of tricks.
If the dealer's team took 4 tens, they win the hand and the turn to deal passes to the right and the kot is removed.
At this point the remaining cards are dealt, potentially making it unverifiable that the player was in fact unable to follow suit.
In the event that all players were able to follow suit in the first five tricks, a random card is drawn from the heap.
[9] Court, coat or kot apparently stands for the achievement in the game, and pees is a Hindi word for to deal.
Immigrants from the Indian subcontinent brought the game to Suriname and Guyana, where it is known as troefcall ("trumps call", a mixture of Dutch and English) and t'rup chaal.
[13] Satat is the most popular game in Mauritius, a group of islands whose majority population is of Indian descent.
