Criss Cross ★★★★★

 A super-simple and addictive game where players have to transfer the symbols rolled to the grid of the block sheet. The more identical symbols are grouped, the more points can be scored. The game is as simple as Sudoku and can also be played alone.

How it is played:
2 dice are rolled and each player has to draw these symbols into their sheet following very simple rules:
- the two symbols have to be drawn in orthogonally adjacent fields. (Single fields previously surrounded with symbols will never be filled.)
- as long as there are adjacent spaces, the symbols must be entered.
The game ends when the sheets are filled or there are no legal adjacent spaces left. Each row and column are scored separately: 2, 3, 4 or 5 adjacent symbols of the same type score 2, 3, 4, 5 points PLUS 4/5 bonus points for 4/5 symbols.

The Grail Games edition of Criss Cross also includes "Advanced" rules which add a layer of complexity to the base game.
