A cross-platform reveal game with a complete content and progression ecosystem.
iOS + AndroidProduct in focus
Picture World combines a relaxed reveal mechanic with the depth of a live game. The player experience, economy and content pipeline were designed as one system so new pictures, stages, collectibles and events can be introduced without rebuilding the app.
The opportunity
Most casual picture games stop at a single repetitive interaction. Picture World was conceived as a deeper product: immediately understandable play with enough variety, progression and ownership to remain rewarding over time.
Our role
ERON Labs owns the complete product: game design, interface and interaction design, cross-platform engineering, content architecture, image-processing tools, commerce, release automation and ongoing quality control.
Product experience
Every supporting mode feeds progress, ownership or creativity back into the same player journey.
Players select a letter and reveal matching tiles by tapping or dragging. Multiple grid styles, zoom, auto-advance, hints, a Magic Brush and persistent progress keep large pictures comfortable to complete.
Artwork is organized into themed worlds with sequential stages, unlock rules, expansion packs and stage rewards. The same structure powers standard pictures, stickers and photo frames.
A Daily Picture, seven-day streak, prize wheel, rotating quests and time-limited celebrations create distinct reasons to return without interrupting the core experience.
Time Challenge converts any completed picture into a fair 400-tile race with Bronze, Silver and Gold goals. Game Mode adds falling letters, combos and milestone reveals directly above the active puzzle.
Completed artwork can be transformed into a wallpaper or share card with custom text, patterns, colours, stickers and frames. A dedicated frame composer places personal photos inside finished frames.
Collections, favourites, achievements, stickers, frames, an editable avatar and My World decor turn progress into something personal and visible.
Coins, boosters, hints, brushes, mystery collectibles, decor and packs form one balanced economy with store purchases and opt-in rewarded advertising.
A parent-gated Kids Mode limits access to age-appropriate content. Fourteen languages, including right-to-left Arabic, are managed through one audited translation layer.
Technology
System architecture
The architecture separates fast player interactions from heavy media, editorial workflows and privileged administration.
One React Native and Expo codebase targets iPhone, iPad and Android with native gestures, audio, haptics, notifications, media export and platform store builds.
Progress, economy, settings and ownership are stored locally with version migrations, defensive data repair, debounced writes and an app-background flush to protect the latest move.
A lightweight catalog is loaded from Supabase while heavy puzzle geometry and images are downloaded only when needed. Opened content is cached for faster repeat play and offline access.
A separate Next.js studio manages puzzle records, statuses, rewards, schedules and storage assets without coupling editorial work to a mobile release.
Python and TypeScript tooling converts source art into puzzle geometry, constrained palettes, thumbnails, silhouettes, outline overlays and export-ready data for several grid types.
EAS profiles support iOS and Android builds, store submission and version-bound over-the-air updates, keeping release configuration alongside the product code.
Security and integrity
Safeguards focus on keeping privileged access out of the app, validating every published asset and making rewards repeat-safe.
The mobile client uses a public anonymous key behind PostgreSQL Row Level Security. Only active, published and currently available content can be read; editorial writes remain privileged.
Supabase service credentials are isolated inside server-only CMS modules and server-side functions. They are not bundled into the mobile application.
Store purchases are handled through RevenueCat and restorable ownership is read from the platform store. Server credit flows use an authenticated webhook instead of trusting client-side balance changes.
Completion rewards, stage bonuses and daily claims are idempotent. Time Challenge only pays the difference when a player improves a medal, preventing repeated reward farming.
Before content goes live, the studio checks metadata, formats, dimensions, palettes, cell data and required storage files. Invalid or incomplete puzzles are reported as non-publishable.
Advertising and purchase wrappers use guarded native loading, cooldowns, timeouts and safe fallbacks so unavailable third-party services cannot block the core game loop.
Automation and scripts
Source images are quantized, converted to playable cells and exported with palette, dimensions, difficulty and reference metadata.
Dedicated scripts create sticker silhouettes, frame cut-outs, outlines and transparent overlays while preserving the correct playable shape.
Avatar parts, decor, home scenes, category artwork and UI assets have repeatable extraction and generation workflows rather than one-off manual edits.
A deterministic audit verifies Time Challenge thresholds, quest rotation, stage unlocking, pack rules, Magic Brush behaviour, combo rewards and ad-bonus timing.
A separate language audit detects missing and fallback strings across the fourteen-locale interface before a release is prepared.
The CMS compares database rows against storage, validates puzzle JSON and catches mismatched dimensions, unsupported formats and missing files.

Results / Current status
Picture World is in active store testing for iOS and Android. The product already operates as a connected ecosystem: the app, content studio, Supabase delivery layer, purchase flows and automated rule checks evolve together.
