There are games for your enjoyment. they are:

**Spider Solitar ** -- The main purpose of the game is to remove all cards from the table,
assembling them in the tableau before removing them. Initially, 54 cards are dealt to the tableau
in ten piles, face down except for the top cards. The tableau piles build down by rank, and in-suit
sequences can be moved together. The 50 remaining cards can be dealt to the tableau ten at a time
when none of the piles are empty.

**Mine Sweeper** -- The objective of the game is to clear a rectangular board containing hidden
"mines" without detonating any of them, with help from clues about number of neighboring mines in
each field. The game originates from the 1960s, and has been written for many computing platforms
in use today. It has many variations and offshoots.

**Sudoku** (数独 sūdoku?, Digit-single) -- originally called Number Place, is a logic-based,
combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each
column, each row, and each of the nine 3×3 sub-grids that compose the grid (also called "boxes",
"blocks", "regions", or "sub-squares") contains all of the digits from 1 to 9. The puzzle setter
provides a partially completed grid, which for a well-posed puzzle has a unique solution.

Completed puzzles are always a type of Latin square with an additional constraint on the contents
of individual regions. For example, the same single integer may not appear twice in the same 9×9
playing board row or column or in any of the nine 3×3 subregions of the 9×9 playing board.

The puzzle was popularized in 1986 by the Japanese puzzle company Nikoli, under the name Sudoku,
meaning single number. It became an international hit in 2005.

**Tetris** -- Tetriminos are game pieces shaped like tetrominoes, geometric shapes composed
of four square blocks each. A random sequence of Tetriminos fall down the playing field (a
rectangular vertical shaft, called the "well" or "matrix"). The objective of the game is to
manipulate these Tetriminos, by moving each one sideways and rotating it by 90 degree units, with
the aim of creating a horizontal line of ten blocks without gaps. When such a line is created,
it disappears, and any block above the deleted line will fall. When a certain number of lines
are cleared, the game enters a new level. As the game progresses, each level causes the Tetriminos
to fall faster, and the game ends when the stack of Tetriminos reaches the top of the playing field
and no new Tetriminos are able to enter. Some games also end after a finite number of levels or lines.
