Slide Escape | 500 Levels Sliding Block HTML5 Puzzle Game

Slide Escape is a complete, ready-to-sell HTML5 sliding-block puzzle built entirely in vanilla HTML5, CSS3, and vanilla JavaScript — no engine, no build step, no external libraries. Open index.html directly, or upload the folder to any host, and it runs.Players drag individual blocks along their axes (horizontal blocks slide left/right, vertical blocks slide up/down) to clear a path for one or two key blocks to reach their glowing exit slots. A warm wooden world – 500 solver-verified puzzles across three difficulty tiers, dual‑key easy levels, sleek wood‑grain UI, and a daily challenge – gives the puzzle real depth without a single external image file.Every visual – icons, HUD, board scenery, exit slots – is hand‑drawn in code (inline SVG + pure CSS), so there are no image files or icon packs to license. The display fonts (Fraunces and Work Sans) are loaded via the Google Fonts CDN (fonts.googleapis.com) – they are not bundled locally. An internet connection is needed on the first visit to fetch them from the CDN; without one, the browser falls back to a default system font and the game still runs normally.How to PlaySlide a block – drag it along its axis (horizontal ⇄ or vertical ⇅). Clear the path so that every key block slides flush against its matching exit wall (right, left, top, or bottom). On dual‑key levels, both keys must escape. The move counter tracks your efficiency – fewer moves earn more stars.Core Gameplay500 solver-verified levels across 3 difficulty tiers:Easy (medium) – dual‑key puzzles with a generous hint budget (3 hints).Hard – single‑key puzzles, more complex block arrangements (2 hints).Expert – single‑key puzzles with minimal hint support (1 hint).Drag & slide controls – touch and mouse both work; blocks only move along their axis and stop when blocked.1–3 star rating per level based on move efficiency vs. the level’s minimum move count.Undo – step back through your moves one at a time.Hints – tap the hint button to highlight the next block to move and show a directional arrow; limited per difficulty.Exit slots – each key block has a dedicated exit side; glow feedback tells you when a key is correctly positioned.Progression & ReplayabilityStar-based progression – unlock the next level by earning at least 1 star on the previous one.Daily Challenge – a fresh seeded level every day; completion resets at midnight local time and shows a countdown.Persistent progress – star collection, daily completion status, and sound preference are saved via localStorage.Synthesized audio – wood‑block “thock” on slide, pleasant chime on win, and light UI clicks – all generated with WebAudio, no external files.Pause menu – resume, restart, or return to the lobby at any time.Visual PresentationRich wood‑grain & brass theme – warm, tactile aesthetic with subtle shimmer animations.100% code-drawn visuals – inline SVG icons, pure CSS wood‑grain patterns, and custom brass accents; no image files.Google Fonts typefaces (Fraunces, Work Sans) – loaded via Google Fonts CDN (third‑party service; internet connection required on first load).Animated background – floating light orbs and a breathing glow add atmosphere without affecting performance.Fully responsive – scales correctly from small phones to wide desktop windows.Documentation/documentation.html Full setup, customization, and FAQ documentationNo build tools, no installation, nothing to compile.Technical SpecificationsBuilt with: Pure HTML5, CSS3, and vanilla JavaScript (no canvas required – DOM‑based rendering)Dependencies: None (game code is self‑contained; Google Fonts are loaded from an external CDN – see Internet Requirement below)Responsive: Yes, across all devicesBrowser compatibility: All current versions of Chrome, Safari, Firefox, and Edge – desktop and mobileInternet requirement: An internet connection is needed once to load the Google Fonts CDN fonts (Fraunces and Work Sans via fonts.googleapis.com).
