Hexillion
Coming SoonA hexagonal puzzle game about connecting matching chips, merging them, and reaching 1,000,000
Overview
Hexillion is a mobile-first puzzle game played on a hexagonal board. Press a chip and drag through adjacent chips of the same value; once the chain reaches the minimum length, releasing merges it into the next number up.
Five 1s make a 5, two 5s make a 10, and so on up the ladder — the goal is to connect two 500,000 chips into a single 1,000,000. Queue the next chain while a merge animation is still playing and a combo multiplier pushes the score much higher.
Features
- 11 × 9 flat-top hex board with drag-to-connect merging
- Merge ladder: 1×5→5, 5×2→10, 10×5→50 … 500,000×2→1,000,000
- Combo multipliers for chains queued during a transition
- Pentatonic scale tied to chain length and chords matched to the merged tile (procedural Web Audio)
- One-move undo and on-board hints when the position gets tight
- Auto-saved progress, best score, and settings; offline play with PWA install
- Google Play Games leaderboard and an ad-free supporter in-app purchase
- Touch, mouse, and stylus handled through one Pointer Event path
Tech Stack
Rendering
DOM/CSS transforms with SVG connection lines - the hex board and its transitions run without a game engine
Language
TypeScript strict mode with React - board transitions managed by a pure reducer
Native
Capacitor 8 Android packaging with Google Play Billing and Play Games Services v2
Audio
Web Audio API - every sound effect and melody synthesized in code, with volume control and preview
Architecture
Each move runs through an explicit transition timeline: merge → per-column gravity → spawn from the top → valid-move check. The logical board is computed ahead of every step and the screen replays that result as animation, so input arriving mid-transition never desyncs the state.
Board, selection, merging, gravity, spawn, and game-over detection are separate pure modules covered by Vitest, and saves use a versioned localStorage schema that stays compatible with data written by earlier releases.
