RAUB Score

Rules of the game can be found here: https://www.pagat.com/rams/raub.html or on other web pages.
Number of players can be set on opening of the app and in settings.
Names of the players can be adjusted by clicking on any, and entering different names.
Points are added or subtracted by clicking on the buttons.
Scores are showed in two places, by each player's name and in score rows, where scores from all players are showed.
When all points for all active players have been adjusted, button "ENTER" should be clicked, and then new scores will be showed in one new row.
When "Add LINE" ("Add DOUBLE SCORE") is clicked, then a line row will be added in score rows, which means that in the next game round, points will be automatically doubled by the app. Those lines can be accumulated, but each can double score only on one game round.
When "Remove LINE" ("Remove DOUBLE SCORE") is clicked, one line row will be removed. This can be used when the line is added by mistake.
If a player is not active in a dealing, then the star symbol is added next to his score. This is an indication on how many times have a player missed dealing rounds in succession. When the player is active, those stars are deleted.
Application is checking if there is an error in entering score, by counting how many points are reduced for all the players in one game round. This should be 4 (or 3 if the player who took the game, won only one hand), and if not so, the error dialog is showed. Also, different error dialog is showed, when scores for players with increasing scores are not according to the rules of the game. This checking can be disabled in Settings of the app (in a case the app is used in some game other from "Raub"). Settings can be reached by clicking the gear icon in the top right corner of the screen. Also in Settings, there is the button "New Game", and when it is clicked, scores and scoring rows are defaulted. There are also settings for changing Number of Players and for changing Starting Points (needed in case of not playing "Raub" game).
If application is used on smaller phones, the buttons are rearranged, as displayed in image.
Happy playing!
