21 durak

- Durak -
Durak (Russian: Дурак; "fool") is a Russian card game. The object of the game is to get rid of all cards. At the end of the game, the last player with cards in their hand is the durak.
The attacker opens the turn by playing one card face up on the table as an attacking card,
the defender attempts to beat the attacking cards by playing defending cards from their hand.
Non-trump attacking cards may be beaten by either a) a higher card of the same suit or b) a trump. Trump -attacking cards may only be beaten by higher trumps.
If the attack succeeds, the defender loses his or her turn and the attack passes. If the attack fails, the defender becomes the next attacker.

Blackjack, also known as twenty-one, is the most widely played casino banking game in the world. Blackjack is a comparing card game between a player and dealer. The object of the game is to beat the dealer in one of the following ways:
Get 21 points on the player's first two cards without a dealer getting 21 too;
Reach a final score higher than the dealer without exceeding 21; or
Let the dealer draw additional cards until his or her hand exceeds 21.
The player are dealt a two-card hand and add together the value of their cards. Face cards (kings, queens, and jacks) are counted as ten points. A player and the dealer can count an ace as 1 point or 11 points. All other cards are counted as the numeric value shown on the card. After receiving their first two cards, players have the option of getting a "hit", or taking an additional card.
The dealer must hit until the cards total 17 or more points.
- War -
The objective of the game is to win all of the cards.
The deck is divided evenly among the players, giving each a down stack. In unison, each player reveals the top card of their deck—this is a "battle"—and the player with the higher card takes both of the cards played and moves them to their stack. Aces are high, and suits are ignored.
If the two cards played are of equal value, then there is a "war". Both players place the next three cards of their pile face down and then another card face-up. The owner of the higher face-up card wins the war and adds all the cards on the table to the bottom of their deck. If the face-up cards are again equal then the battle repeats with another set of face-down/up cards. This repeats until one player's face-up card is higher than their opponent's.
