HTML5 Puzzle Game Source Code: What You Get and What to Check
Levels, the daily puzzle, TypeScript source and hosting for a finished logic puzzle, using Frogdoku as the example.
Free HTML5 game code is easy to find. Finished, tested puzzle games with real levels, a daily puzzle and documented source are harder to find, and they are what most buyers mean when they search for source code they can ship.
Frogdoku is a logic puzzle with one rule: place exactly one frog in every row, every column and every coloured pond, with no two frogs touching. This guide shows what to check in any puzzle template, using this edition as the example.
Start with the level count and the modes
The buyer edition includes 180 campaign puzzles in six stretches of a stream, a daily puzzle calendar, Endless and Relax modes, trophies, undo and redo, and helpers. Ribi's wardrobe is a reward for progress.
Level count matters more than the cover. A template with 20 levels is closer to a prototype, while one with 180 is closer to a finished game. Ask the seller how the levels were made and how each one was checked, because a puzzle the player cannot solve is the fastest way to lose them.
What the source code includes
The source is written in TypeScript and comes with tests and third-party licence notices. The package lists JSON among its files, and the game folder is the ready-to-host build with local artwork, audio and fonts.
- game/: the ready-to-host build, with artwork, audio and fonts already local.
- The TypeScript source and its tests: the part you read and edit.
- Vite: optional, and only needed if you rebuild from the TypeScript.
A 15-minute check before you buy
You can judge a puzzle template in a short session. Play the first stretch on a phone, then on a laptop, and note where a tap or a drag feels slow or unclear. Undo the last move several times, and check that the board returns to the earlier state each time.
Then open the source and read the test names. Look for tests named after the rules of the puzzle. A rule that has a test is enforced in code, not only shown on screen.
Hosting: static files only
Like the other templates in this guide, the buyer edition needs a current browser with JavaScript and audio support and static HTTP(S) hosting. It needs no database and no author account.
Upload the contents of game/ to the folder where the puzzle should live. Rebuilding is only needed if you change the TypeScript source.

What the price leaves out
Frogdoku has no cloud saves, no online ranking, no real-money purchases and no advertising SDK, and normal play makes no requests to such services. Progress is saved in the current browser.
Native apps, hosting and custom development are not included. The daily puzzle is part of a calendar and does not need an online ranking to play.
Frequently asked questions
Do I need to build the game?
No. Upload the contents of game/ to HTTP(S) hosting. Rebuilding is needed only if you edit the TypeScript source.
Where is progress saved?
Locally, in the current browser.
Does the daily puzzle need an online ranking?
No. Daily puzzles stay playable without one, and progress is saved in the player's browser.
What licence applies?
The Polar Games Marketplace terms shown at checkout apply.
Where a puzzle template earns its place
A puzzle like this suits a learning site, a daily-puzzle habit on a blog, or a studio that wants a finished logic game to customise. It is a poor fit for a project that needs ranked play or accounts, because those are outside this edition.
