Worked examples
Try Tic Tac Toe with the sample values
Run the tool once with the example values already shown in the form. This lets you see the output format before replacing them with your own information.
Compare a second scenario
Change one input while keeping the others the same. Comparing two runs is the easiest way to see which value has the biggest effect on the result.
Check the units before using the answer
Before using the result elsewhere, confirm that the units and input format match the figures you started with.
When this tool is useful
- Killing a few minutes with a quick classic arcade game — no install, no sign-up.
- Building a quick range — best, base, and tight — by varying one field in Tic Tac Toe.

How to play Tic Tac Toe
You play X and move first. Click or tap any empty square.
Against the computer, it replies as O after a short pause. In 2-player mode, take turns on the same screen.
Get three of your marks in a row — horizontally, vertically, or diagonally — to win the round.
No download or account is needed — the game starts instantly in this page.
Scoring
Wins, losses, and draws are tallied across rounds at the top of the board.
Tips for a better score
- Take the centre square when it is free — it participates in the most winning lines.
- Always block an opponent who has two in a row with an empty third square.
- Corners are stronger than edges for building two threats at once.
Controls
- Desktop: arrow keys or WASD where movement matters; mouse or trackpad clicks elsewhere.
- Mobile: swipe or tap directly on the game board.
- Restart: use the Restart button above the game to reset the round at any time.
Common mistakes to avoid
- Starting at full speed before learning the controls — spend one slow round on the basics first.
- Playing tilted after a loss instead of restarting fresh; scores recover faster with a reset.
- On mobile, tapping frantically during animations can queue accidental moves.
- Ignoring the keyboard on desktop — arrows or WASD are usually faster than clicking.
