A calm little break, one click away.
RuBuild Puzzles puts two relaxing puzzle games in your browser toolbar. Sort colours into jars, or fit blocks to clear lines. No sign-up, no ads, no timers.
- Free to play every day
- Works offline
- Nothing to sign up for
Two gentle games. Pick your mood.
Switch between them any time from the top of the game window.
Sort the colours
Tap a jar to pick up its top colour, then tap another jar to pour. Make every jar hold just one colour. Levels get gently harder as you go, and there's a fresh daily challenge that is the same for everyone. Keep your streak going and share your result with friends.
Tap the pictures to see more.
Fit and clear
Drag shapes onto the 8×8 board. Fill a whole row or column and it clears with a satisfying pop. Before you drop, the line that will clear glows, so you always know what's going to happen. Turn any shape with the ↻ button, a right-click or the R key. Each kind of shape has its own colour, so the board stays tidy and easy to read.

RuBuild Puzzles FAQ
Is RuBuild Puzzles free?
Yes. You can play 10 Jars levels, 5 Blocks games and the daily challenge free, every day, with no time limit. Pro is an optional one-time upgrade for unlimited play and extras.
Do I need an account or to sign in?
No. There is no account and nothing to sign up for.
Which browsers does it work in?
Microsoft Edge and Google Chrome on Windows, Mac and Linux computers. It isn't available for phones yet.
Does it work offline?
Yes. Once installed, both games work without internet.
Is Pro a subscription?
No. You pay once and keep Pro. There are no monthly charges.
How do I pay?
Payments are handled by Razorpay, a secure, RBI-regulated payment gateway. In India you can pay by UPI, card, net banking or wallet. Outside India you can pay by international card. RuBuild never sees or stores your card or bank details.
When will I get my Pro key?
By email, usually within a few hours and always within 24 hours of payment. Check your spam or promotions folder too. If it hasn't arrived after 24 hours, email us with your Razorpay payment ID.
Can I use my Pro key on more than one computer?
Yes. Your key is for your personal use, and you can activate it in RuBuild Puzzles on any of your own computers, in Edge or Chrome. Please don't share it publicly.
I lost my Pro key. What do I do?
Email us from the address you paid with, or include your Razorpay payment ID, and we'll send it again.
Where is my progress saved?
Only in your browser on your computer. Nothing is sent to us or anyone else.
What happens if I close or restart my browser or computer?
Nothing is lost. Your levels, streak, scores and Pro stay exactly as they were.
What happens if I uninstall the extension, reset my browser, or move to a new computer?
Uninstalling removes the game's saved progress (levels, streak, scores) from that browser, and it can't be recovered because we never have a copy. Resetting your browser's settings usually just turns extensions off; turn RuBuild Puzzles back on in your browser's extensions page. If your progress is gone, Pro is not: reinstall, tap Get Pro, and paste your key again. Keep your key email somewhere safe.
Does clearing my browsing history or cookies delete my progress?
Normally no. Extension data is kept separately from website cookies and history.
Does the game collect my data or show ads?
No. There are no ads, no tracking and no analytics. See our Privacy policy.
What permissions does it ask for, and why?
Only "storage", so it can save your progress in your browser. It can't read the websites you visit.
Is it suitable for children?
Yes. The games are gentle and contain no ads, chat or in-game messages. Buying Pro needs an adult's payment method.
Will there be updates?
RuBuild Puzzles is complete and designed to keep working without updates. If your browser ever needs one, we'll release it free for everyone, including Pro owners.
Who makes RuBuild Puzzles?
RuBuild Services, an independent software publisher in India. We also make RuBuild Panel, a quick-access side panel for Edge and Chrome.
