How to Solve Alternate Corners Puzzles
Draw a single closed loop that passes through every cell without branching or crossing itself. It makes a right-angle turn in every circle, and exactly one turn between each pair of circles.
How to Solve Arrow Maze Puzzles
Label all the arrows with a number from 1 to X (X is the highest possible number) showing the correct sequence of arrows. Each arrow points to the next in the sequence, but it’s not necessarily adjacent.
How to Solve Arukone Puzzles
Connect each pair with a line that only travels orthogonally. These paths do not cross and might not use every cell in the grid.
How to Solve Gokigen Puzzles
Place diagonal lines in every cell so that there are no closed loops. Circled numbers indicate how many lines touch that intersection.
How to Solve Hashi Puzzles
Draw bridges between islands to create one connected group. Numbers on the islands indicate the number of bridges that connect to that island.
How to Solve Hiroimono Puzzles
Fill in the stones with numbers to show the correct order to pick them up, moving from one stone to another by the grid lines.
How to Solve Ichimaga Puzzles
Connect all the circles by darkening lines on the grid. Numbers indicate how many lines are connected. Lines may make no more than one right-angle turn between circles.
How to Solve Kin-Kon-Kan Puzzles
Place a diagonal mirror in one cell of each region. Matching letter-number combinations outside the grid indicate the start and end of beams that reflect off a given number of mirrors.
How to Solve Masyu Puzzles
Create a single closed loop which passes through all the circles, but not necessarily all the cells, without crossing itself or branching. Black and white circles have different rules about how the line of the loop passes through them.
How to Solve Milk Tea Puzzles
Connect pairs of white “milk” circles with single black “tea” circles in T shapes that may not touch or cross each other.
