How to Solve 100 Rubiks with Simple Formulas

The Rubik's Cube, invented by Ernö Rubik in 1974, is an intelligent, fun game, that was the world's best-selling game of the twentieth century, and is still in vogue today.
The original Rubik's Cube, or the Standard Rubik, is a six-sided, six-color cube, cut by six slices, distributed on three axes of Oxyz coordinate system, yielding 27 (3*3*3) Rubik's pieces.
The Standard Rubik has many standard variants, which are variations on the pattern of Rubik's faces, on the Rubik's body shape, on distribution and direction of the cutting planes, on the shape of cutting surfaces, on the size of variants, and on the number of axes of variants.
There are also many Non-Standard Variants, which are variants in size, in shape, in center of rotation, and in transmission when rotating the Rubik's body.
This book sequentially shows how to solve 100 Rubiks, including the Standard Rubik, 72 Standard Variants, and 27 Non-Standard Variants.
There are many ways to solve the standard Rubik's Cube, this book uses the pRubik procedure to solve it. The pRubik procedure consists of 3 steps, using 9 formulas, each consisting of a number of simple rotation steps. Of these 9 formulas, there are 2 pairs with 4 dual formulas, and 2 similar formulas, so actually only 6 independent formulas, therefore it's easy to remember the procedure.
72 standard variants to be solved include 36 simple variants and 36 complex variants. All of these standard variants can be solved using the pRubik procedure.
Simple variants include: Void 1, Potato Chips, Convex Concave, Sandwich 1, Colored Corner, Red Cap, House of Science, Cylinder, Octagonal Prism, Void 2, Ball, Ball in Cube, C-Virus, Anis Star, Twisted Cube, House 1, Mirror Cube, Colour Cube, Fisher, Windmill, Mirror Fisher, Mirror Windmill, Fluffy, Pandora, Sandwich 2, Rainbow 1, Rainbow 2, 2*2*2 Cube, 2*2*2 Mirror Cube, Window, 2*2*2 Megaminx, 2*2*2 House, Mouse, Buffalo, Elephant, Cat.
Complex variants include: Maze 1, Maze 2, Arrow, Shepherd, Dice, Blackpink, Chemistry, Math 1, Math 2, Number, Sudoku, Case, House 2, Penrose, Star, Egg, Heart, Orange, Peach, Lemon, Pear, Apple, Hexagonal Dipyramid, Hexagonal Diamond, Hexagonal UFO, 4-Corner, Mastermorphix, Axis, Mirror Axis, Crazy Fisher, Crazy Windmill, Ghost, Phoenix, Kilominx, Megaminx, Phoenix Megaminx.
27 Non-Standard Variants to be sovled include: 1*2*2 Rubik, 1*2*3 Rubik, Pine, Rubik 1*3*3, Spinner, 2*2*3 Rubik, Banana, 2*3*3 Rubik, Cylinder, 2*2*2 Pyraminx, 2*2*2 Mastermorphix, Pyraminx, Coin Pyraminx, Petal Pyraminx, Duomo Pyraminx, Clover Pyraminx, Dino, Ivy, Six Spot, Skewb, Fisher Skewb, Twisty Skewb, Redi, Barrel, Butterfly, Gear Cube, Gear Pyraminx.
The author hopes that readers will have an enjoyable time, reading this book to learn and solve the above 100 Rubiks.
