4 Xmas

## Description

_4 Xmas_ is a falling blocks puzzle game with a Christmas theme. The aim of
the game is to clear Christmas balls that fall from the top of the screen.
Each ball has one of four letters (X, M, A, S) and they has to be combined so
that the word Xmas is created and the balls are then eliminated from the
screen. Chains can be created vertically, horizontally or in any shape as long
as the letters are connect adjacently in the right order. It is also possible
to create multiple chains and combos. Some special events affect the game such
as rising and falling snow levels which influence the difficulty, special
balls that act as jokers and the possibility to launch the Grinch which can
crash through balls.
