Four logic games from one book chapter, chosen from a menu. In The Pattern Game one player makes a hidden pattern of dots, stars and crosses on a 4 x 4 grid, and a friend reconstructs it, asking for clues when stuck; each clue reveals one square, and the game ends with "YOU DID IT WITH n CLUES". The 3 x 3 and 4 x 4 Number Puzzlers are the old sliding block puzzles: the numbers are shuffled, you move the empty square, and a counter shows how many numbers are already in place. In Dozo, a warm-up game of Japanese Go masters, two sides take turns placing any of four kinds of piece, which belong to nobody, on a triangle of 28 points; the first to complete an equilateral triangle of any size and slant with three identical pieces wins. You play Dozo against the computer, which takes a winning move when it has one and otherwise avoids handing you a triangle.

The rules follow the book's Atari listings line by line. The ColecoVision version puts the three programs on one cartridge with a menu, frames the number blocks, uses joystick menus for the yes/no questions and adds an editorial page. The book's Number Puzzler mix can be impossible to solve, as the chapter itself explains with Sam Loyd's 14-15 Puzzle, so you can choose the book's random mix or a mix made by random slides, which is always solvable, and a message now tells you when the puzzle is solved. The 126 Dozo triangles, which the book lists as 756 DATA bytes, are computed instead.

Controls: the joystick moves the cursor. In The Pattern Game, button 1 changes a square's symbol, and button 2 or keypad # finishes the hidden pattern; while guessing, button 2 or keypad * asks for a clue. In the Number Puzzlers the stick slides the empty square, and button 2 or keypad * returns to the menu. In Dozo, button 1 places a piece, button 2 or keypad 1 to 4 changes the piece, and keypad * returns to the menu.
