A complete, production-ready HTML5 logic-puzzle game built for commercial distribution. Zero external JavaScript dependencies. Runs on any modern browser straight from a static file host with no build step required.
Overview
Logic Lattice bundles three Sudoku variants on one shared 9×9 engine: Mathdoku Towers (bold-outlined cages that must satisfy a +, −, ×, or ÷ equation, with no repeated digit inside a cage), Consecutive Sudoku (classic Sudoku with dots marking every pair of neighboring cells whose final digits are consecutive), and Arrow Sum Sudoku (classic Sudoku where the digits along each arrow must add up to the circled digit at its start). Every puzzle is generated procedurally at play time — there is no bundled puzzle list.
Logic Lattice game features Easy/Medium/Hard difficulty tiers plus a seeded Daily Challenge, five selectable board themes (each with its own fixed background image), an optional Cartoonic Mode visual style, a shared XP progression system with seven rank tiers, a local best-times leaderboard, an eight-achievement system, a configurable hint system, and a full sponsor/ad integration framework — all in a single self-contained HTML5 package.
About the Game
Entry point is index.html — no build step, no CLI tools, no package manager required
Pure vanilla HTML5, CSS3, and ES6+ JavaScript — zero libraries, zero frameworks
Game engine and UI for all three puzzle modes are contained in a single IIFE in scripts/js/game.js
There is no bundled puzzle file — Mathdoku Towers, Consecutive Sudoku, and Arrow Sum Sudoku boards are all generated algorithmically at runtime, for every difficulty tier
All CSS lives in scripts/css/style.css; sponsor/ad placeholder in scripts/sponsor/sponsor-placeholder.html
Daily — a puzzle unique to each player, seeded from today’s date plus a per-device player ID, built at a configurable difficulty (Medium by default via dailyDifficulty). No server or puzzle database — a fresh puzzle is generated every calendar day and never repeats. The Daily Challenge is shared across all three modes: completing it once, in any mode, marks the Daily card done for that calendar day everywhere, and unlocks again automatically the next day.
Logic Lattice grid is always 9×9 for every mode and difficulty — difficulty controls cage size and operator count (Mathdoku Towers) or how many digits/arrows are pre-filled (Consecutive, Arrow Sum), not the grid size itself.
Import Puzzle (All Modes)
On the difficulty screen, in any of the three modes, players can paste a complete, already-solved 81-digit grid (digits 1–9, no zeros) into the Import Puzzle panel. The game validates that every row and column is legal (and every 3×3 box too, for Consecutive and Arrow Sum Sudoku), then builds the puzzle around it using whichever mode is currently selected — Mathdoku cages, Consecutive dots, or Arrow Sum arrows — at Medium complexity, and loads it as a custom puzzle. Custom puzzles are not recorded on the leaderboard.
Themes
Five board themes are selectable from the “Board · Style” screen, shared across all puzzle modes. Each theme owns one fixed background image — there is no separate background picker. The active theme is saved to localStorage and restored on every visit. The default theme is Warm Paper.
