Shifting Tiles

Rules

The goal of this game is to score more points than your opponent by matching cards in your hand to the tiles in the grid.

Each player is dealt 4 cards, then they take turns until someone scores 10 cards.

During your turn you can do any of the following:

Score a card - if one of your cards matches the tiles in the grid, move it to your “Scored” area.
Discard a card - move any of your card to a discard pile, next to the deck. That allows you one manipulation of the grid.
Manipulate the grid - you can either flip one of the tiles over or swap any two tiles that are touching by their sides. For that, you would first have to discard one of your cards.
Skip a turn - if you haven’t played any of your cards, you can skip your turn and get two more cards. You can only do that once in a raw.
End a turn - get new cards from the deck and switch a turn to another player.

The grid consists of 9 tiles laid out in 3 rows of 3 tiles each. The tiles have different colors and shapes on each side:

For your convenience, the Guide card with the images of both sides of each tile is always displayed on the screen.
