Sudoku Tips & Tricks

Learn How to Play Sudoku

Sudoku is a logic puzzle where you fill a 9x9 grid with numbers. No math required, just reasoning. This guide walks you through our game interface and gives you strategies to tackle even the hard puzzles.

Last Free Cell

When you have eight numbers in a row, column, or 3x3 box, the ninth is obvious. This technique is where everyone starts.

Naked Singles

Sometimes a cell looks at its row, column, and box, and after all the eliminations, only one number is possible. That is a naked single.

Hidden Singles

A hidden single is sneaky. A cell might accept several numbers, but when you check where a specific number can go in a row, column, or box, only that cell works.

Naked Pairs

When two cells in the same row, column, or box can only contain the same two numbers, those numbers cannot appear anywhere else in that group. Simple idea, big results.

Hidden Pairs

A hidden pair is like a naked pair, but buried among other candidates. Two numbers appear in only two cells within a group. The other candidates in those cells are distractions.

Tic Tac Toe Tips

Learn to Play Tic Tac Toe

Tic Tac Toe is one of those games you probably learned as a kid. Two players, a 3x3 grid, Xs and Os. Simple enough that anyone can play, but there is more to it if you want to actually win.

Center and Corners

Most casual players pick random squares. But the center and corners are significantly better starting positions. Here is why.

Blocking and Winning

Many players lose because they block when they could win, or miss threats entirely. Here is a checklist that fixes both problems.

The Fork

A fork is when one move creates two winning threats. Your opponent can only block one, so you win. Once you see how forks work, you will spot them everywhere.
