- Optional integrations: Google Mobile Ads/AdMob, LevelPlay, AppsFlyer and platform services require separate SDKs and buyer credentials; SDK binaries are not bundled

Official Google-served test-ad shots in the promo are separately recorded evidence. Configure production IDs, consent and vendor SDKs before release
- Verified build targets: See current build receipts and validation status in publishing evidence
- Supported project targets: Android and WebGL; Windows used for buyer-import gameplay validation. iOS/native-device acceptance is not certified
- Known limitations: The conservative permanent-wall reachability audit reports 94 existing route warnings while all 500 current winning certificates pass. These warnings do not prove impossible levels or exhaustive safety for every player order. Human difficulty balance remains unmeasured. Native level-editor captures are below the preferred marketing source resolution but remain readable. Production signing, privacy/consent, store products, live ad/billing/account certification and original game provenance confirmation remain pending
A box needs the right colour above it and a clear route through the board. Sand Blocks gives you a timed sand-filling puzzle to retheme, extend and tune, with a 500-level campaign and the tools that author its boards and tank queues.

⏳ Make each move count before the timer ends
Drag boxes through free cells beneath glass tank columns. Matching sand pours into a resting box; a full box clears its footprint and makes room for the next move. Fill every box to win, or reach zero on the countdown to lose. A supplied solution is replayed through the same simulation that runs the game.
🏗️ Build the board and its supply together
Paint the playable area and walls, reshape pieces and tanks, edit queued colour layers and place covers, keys or locks. Rebuild sand and a winning witness for a custom board, then validate it. The seeded generator supports append mode, cancellation and managed publication with backups. New candidates also pass the conservative permanent-wall route guard and timer replay.
🧱 Reveal new planning problems across the campaign
Nine board families introduce corridors, steps, pillars, channels, covered boards, towers, pockets and vaults. Layered supplies, numbered covers, hidden boxes, keys and pipe-fed tanks change which route is useful next. The two recorded source boards occupy levels 1 and 200. All 500 current winning certificates pass; this proves those solutions and does not establish safety for every possible move order.
🛠️ Offer three distinct ways out of a difficult board
Freeze pauses the countdown for ten seconds. Hammer fills one valid targeted box using the tank supply. UFO fills all boxes of the targeted colour and removes that colour's queued sand. Persistent unlocks at levels 2, 7 and 12 grant two initial charges once; the shared bar explains each action and handles coin or rewarded refills.
📱 Connect the puzzle to a reusable product shell
The included first-party HyperCasualLiveOpsKit supplies the menu, level selector, results, economy, rewards and retention systems. Ads are included as provider adapters. Downloadable demos use local/mock configuration; separate vendor SDKs, consent, production IDs, store products and signing are buyer setup. Import the documented URP project roots, use Unity-provided fonts and retheme the supplied materials, palettes and feedback. Current Android/WebGL build evidence and the game-specific guide accompany the package.
