What is the Thousand (1000) - card game game, how does it work?

According to the introduction of Card Games Development, Thousand (1000) - card game is a Card game on the Android platform. There is currently a 1.0.2 version released on Mar 21, 2020, you can see the details below.

- to get a barrel a player need to get 880 points
- clear points if a player has 3 unsuccessful tries to play barrel
- a player gets bolt if he does not get points in round
- if a player has 3 bolts then it gets 120 points fine
- in case of giving up the player has a fine same as a statement and each of rest two players gets half of that amount

The game supports the following settings:
- to win the game need to gain greater than 1000 points
- clear points if a player gets 555 or -555 points
- a barrel game on own turn without bidding from other players (see below)
- new card distribution if talon or hand has fewer points than some threshold

What is not supported yet:
- ace marriage
- golden round
- hidden game
- together barrel playing cases
- "4 nines" marriage

Barrel game on "own turn”:
A player can play barrel round if he has 880 points and "own turn".
The turn is "own" if a player has a right of the first call on bidding.
In that case, the player wins the bidding and receives the talon (despite the strength of the cards of other players).
In case of an unsuccessful game, he gets an unsuccessful try and the player gets 120 points fine.
After 3 unsuccessful tries, the points are cleared.
When a player in a barrel and does not have "own turn" the game passes as usual, but he does not get any points (unsuccessful try also is not accounted).
Also, it is not forbidden if several players simultaneously have 880 points and have the opportunity to play a barrel game.
Thus, in that situation, a barrel player is determined according to turn.
