About this challenge
Rocket and Planet is challenge 5 in the ten-part Three in a Row collection. It uses the same core rules as the other challenges in this family, with its own settings: computer foresight: 50%. Choose it when you want a medium round, or use the previous and next buttons to adjust the challenge.
Rules and controls
Place the rocket marks against the computer’s planet marks and complete a line of three. Click or tap an empty square. Your piece is the rocket. Your result appears above the board when the round ends. Restart begins a new round; it does not continue the previous board. The game keeps a small record of completed rounds in this browser.
Make your next round better
The centre participates in four winning lines. Corners are useful for creating two threats. Look for a winning move first, then block a direct loss. A draw is a valid result. If the current challenge feels too demanding, go back one level and focus on the basic pattern before increasing the pace or board size.
Playing on a phone
The board adapts to the width of your screen. Use the displayed buttons or direct touch controls. For word and number inputs, tap the text field to bring up the keyboard. Put your phone in portrait orientation for the clearest view of the controls. Timing games may feel different across devices because screens and input hardware respond at different speeds.
Part of a collection, with a clear goal
This is one of ten variations of Three in a Row, not a separate game engine. PLAYDAY contains 30 game types and 300 playable challenges in total. Each challenge has an individual page so you can return to the rules, save a favourite and choose a suitable level.
