For partners | Honest Blocks

In one paragraph

Honest Blocks: Block Puzzle is a free Android block puzzle, in one of the most played casual genres on Google Play. It stands apart on one idea: it plays fair. No ad interrupts a game, pieces are random from published odds, and one purchase removes every ad. Behind that promise is a full game: four modes, 300 checked levels, a server that verifies every leaderboard score, 20 languages, and a codebase written so iPhone can be added without a rewrite.

Why it is different

A brand players can check. The odds of every piece are published, and any game can be dealt again in a browser from its code.
Fair leaderboards. The server replays every submitted game move by move with the same rules engine as the app. Scores that do not match are refused.
Revenue without pressure. Ads between games under clear published rules, plus one non-consumable purchase. No coin packs, no subscriptions, no limited-time offers.
Privacy by design. No account of ours, no analytics or tracking SDKs, generated names only, and the IP address is never stored.
A story people share. Two daughters asked their dad for a game that would never cheat. Read it.

What is built

Classic: The endless mode, with a live “vs best” line, one undo per game and share cards.
Daily Puzzle: The same pieces for everyone each day, Daily stars, a streak with a rest day, and replays of each day's #1 game.
Adventure: 300 levels in six worlds of 50, every one beaten by an offline solver with no boosters before it shipped. Fixed prizes, boosters and collectable picture cards.
Battle Blocks: A link that gives a friend the exact same pieces, with the verified result sent back to the challenger.
Competition: Country and world leaderboards, a weekly Country Cup and weekly leagues in ten tiers.
Progression: A player level from 1 to 999, 58 achievements, three daily goals and seasonal looks, all earned by playing.
Shop: Block styles, photo backgrounds and sound packs bought with coins earned in play. Coins are never sold.
Google Play Games: Achievements, two Play leaderboards and a cloud save that brings progress back on a new phone.
Reach: 20 languages in the game and a store listing in 10. Large text, high contrast, colour-blind patterns and haptics.
Phone extras: Daily reminder, home screen widget, app shortcuts and in-app updates.

Technology

App: Flutter (Dart), drawn with CustomPainter. Android today; the same code is ready for iPhone.
Server: Cloudflare Workers (TypeScript) with a D1 database. It runs within Cloudflare's free tier today.
Rules engine: One rules engine and seeded random generator written twice, in Dart and TypeScript, kept identical by shared recorded games.
Content: Music and photographs are downloaded from a content server when first needed and checked by SHA-256, so the app stays small and new content needs no update.
Size: About 32 MB to install on a modern Android phone.
Quality: More than 6,600 automated tests in the app, a server test suite, and checks for privacy, ad rules, licences and download size on every build.
Offline: Classic, Adventure and the Daily Puzzle play with no connection. No network call ever blocks a game.
