PetDoku guides
PetDoku is a logic puzzle where one pet hides in every color region. Each row, each column and each color holds exactly one pet, and two pets never touch, not even diagonally. The three guides below go from an easy board to an 8 x 8 hard one, starting with a color that has only one cell left and ending with groups of two and three colors that share the same rows. The same hints work in any Queens-style puzzle.

Kaku guides
Kaku is a Shikaku puzzle: you split the board into rectangles so that every rectangle holds exactly one number, and that number is its area. The beginner guide starts with numbers that can only take one shape. The intermediate and advanced guides move to boards of 8 x 8 and larger, where you track how far each number can reach and, when nothing else works, try a shape in your head to see where it breaks.

Nonogram guides
A nonogram hides a picture behind the numbers on each row and column. The numbers tell you, in order, how long each run of filled cells is in that line. The guides start on a 10 x 10 Simple board with the basic hints, then move to 15 x 15 and 20 x 20 boards, where you split lines with X marks, clear gaps that are too short and work out which number each filled run belongs to.

Block Link guides
Block Link is a one-stroke puzzle: start at the white ring, pass through every block exactly once moving up, down, left or right, and finish on the star. The beginner guide shows how to read the board before you draw, from blocks with only two neighbors to keeping the ring and the star apart. The intermediate guide covers bigger boards with many possible routes, where you pick a branch, avoid closing a loop and test a move in your head.

Ten Link guides
Ten Link is a number-pair puzzle: clear two numbers that match or add up to ten whenever the path between them is open, in a straight line or in reading order. Each of these three guides solves one real Daily Challenge board move by move. They start with the color rule and reading-order pairs, move on to spotting trap pairs before they ruin a board, and end with counting odd colors and clearing a full 54-square board from the inside out.

Love Ladder guides
Love Ladder is a ladder-drawing puzzle: each animal walks down its own line, crosses every rung it meets, and has to reach its partner at the bottom. You decide which of five pieces goes in each slot. These three guides solve real stages step by step. The beginner guide reads the middle order and single slots, the intermediate guide explains how neighbouring pieces behave, and the advanced guide splits long rows and tries pieces in your head.

Crossum guides
Crossum is a crossword made of sums: fill the empty cells with every number from the tray so that each equation across and down is true, with multiplication and division done first. These three guides solve one real board each, from Easy 38 through Normal 9 to Hard 141, covering simple calculation and tray pairs, crossing cells and trials in your head, and long two-operator equations on the big 11 by 11 boards.
