The cross method: read patterns faster
The single technique that drops move counts on every board size.
Everything players actually ask about Ruby Square — gameplay, levels, purchases, devices and privacy — collected in one place. Still stuck after this? The contacts page reaches a human.
The six questions that account for most of our inbox.
Tap a block of squares to rotate it 90°. Keep rotating blocks until your board matches the small target pattern beside it. Fewer moves = better — the world average is shown on every level as your par.
Yes — all 700+ levels across eight stages are free with occasional ads. The A$0.99 premium upgrade removes ads permanently. Nothing else is locked. Full details on the price page.
Every level is solvable — each scramble is generated by rotating away from solved. Try undoing to a clean state, work corners first, and if you want the deep techniques, the Strategy Guide Vault covers them all.
Yes — sign in to Google Play Games inside the app and your solved levels and move records follow your account to any Android device.
Rated Everyone and Teacher Approved by Google. There's no chat, no user-generated content and no required purchases. Our parents' guide has the full picture.
No — once installed, every feature works fully offline. Internet is only used for cloud save sync and updates.
The rules are tiny; the questions they spawn are not.
Unlimited undos — one tap steps you back a rotation, and you can walk the whole game backwards if needed. Undoing doesn't count against your move total on most stages.
Each level stores the average number of rotations real players needed to solve it. It's your par — beat it and the level marks as under-par on your record.
Yes — hints suggest the next useful rotation without solving the board for you. Using a hint doesn't lock you out of achievements.
A 4x4 rotation moves 16 cells — four times the board disruption of 2x2. Planning becomes mandatory rather than optional; that's the intended difficulty wall and what our pattern-reading guide addresses.
Stages progress by board size (16→64 squares), palette size (2→6 colors) and block size mix (2x2→4x4). Easy, Medium, Hard and Extreme tiers each contain multiple stages.
Within a stage, yes — levels unlock sequentially. Between stages you can jump ahead if earlier stages bore you.
The studio has shipped new packs in waves since 2018. The next stage is in testing — follow the blog for announcements.
| Easy stages | 1–2 · ~150 levels |
| Medium stages | 3–4 · ~200 levels |
| Hard stages | 5–6 · ~200 levels |
| Extreme stages | 7–8 · ~150 levels |
Tap the upgrade button in the app — a single A$0.99 Google Play purchase removes ads forever, across all your devices tied to the same account.
Usually a sync delay: restart the app with internet available so the purchase can verify. If it persists past 24h, contact us via contacts with your order ID.
In-app purchases follow Google Play's refund flow. Portal services carry a straight 14-day money-back promise — see the refund policy.
Roughly: Google's billing fee (~15–30%), then the rest funds level design, device testing and the servers behind world averages. No investors, no ad-tech middlemen.
Portal services come with proper GST invoices — schools and businesses can expense them cleanly. Request via contacts.
Almost certainly — Android 4.4 (2013) and up, ~15 MB install, and designed to run smooth on budget hardware.
Yes — the layout adapts: on wide screens the target pattern sits beside the board rather than above it, and foldables transition cleanly on unfold.
Rare but possible: update to the latest version first. Still crashing? Send device model + Android version via contacts — crash reports get priority.
Yes — a dedicated colorblind-friendly palette ships in the base game, and our accessibility service tunes it further per player.
Yes — the night palette lowers luminance while keeping contrast AAA-readable for late sessions.
An hour of play costs roughly 9% on a mid-range phone — it's a static board with no background services, not a 3D engine.
Very little: level progress, move counts and anonymous crash diagnostics. If you sign in to Google Play Games, sync uses your Google account — we never see your password. Full detail in the privacy policy.
No — there's no ad-tech profile to sell. The game shows ads from Google's network; gameplay analytics stay aggregate.
Email us via contacts with "data deletion" in the subject — progress and any portal records are removed within 30 days, per our legal page.
The large grid you're solving — 16 to 64 colored squares.
The small reference grid showing the arrangement to reproduce.
A rotatable group — 2x2, 3x3 or 4x4 squares — that spins 90° per tap.
The average move count other players needed. Beating it marks a level under-par.
A themed pack of 50–100 levels sharing a difficulty profile.
A suggested next rotation — helpful, never a full solution.
Solving a board in fewer moves than the world average.
Community shorthand for the final Extreme stage pack.
The single technique that drops move counts on every board size.
Why some boards can't be solved in even moves — and how to spot them.
A sustainable daily routine that compounds into real board vision.
