Here are all the details:
The objective is to fill a 4×4 grid with cards (ace, king, queen, jack) so that each column, each row, and each of the four 2×2 sub-regions that compose the grid have one and only one card of each rank (the card suit is taken care of by the program).
The initial layout is a partially filled grid with 6 cards.
Generally, it is not difficult to solve it in the Practice mode: the 4x4 grid is very suitable for younger or beginner players and is good to learn the sudoku game basic logic. However, playing with a timer is electrifying - you have to think and tap fast. Playing with a covered card presents an additional challenge.
When the move is made against a rule the "bad" card is placed. Tap it again to remove.
Undo button allows to roll back all made moves in reverse order.
In the "Practice" ("P" button on an iPhone) mode there is no time limit, good for training. The Hints also serve as a training aid.
When playing against the timer the time limit can be set to 20, 30, 45, 60, and 100 seconds in the standard mode and to much shorter times in the Pro Timer mode. The progress bar length indicates the time left, its color varies from friendly green to an alarming red.
The covered card is revealed when its value is pretty much evident.
When playing with hints the playing time does not count against top 10 times list (evidently fair). Hints are self-explanatory: a cross for forbidden position, a tick sign for allowed, and a question mark for unknown (the last one is only used when playing with a covered card).
