The answer depends on which game you mean. “Hardest Game On Earth” is listed on MarketJS, a licensing marketplace for HTML5 games, and the listing does not name an individual creator. If you meant “World’s Hardest Game,” a separate and older title, Coolmath Games attributes it to the developer Snubby Land. The phrase “hardest game on earth” is also promotional wording, not a verified ranking, so the question has a credit answer but no objective “hardest” answer.
Which game are you asking about?
Two similarly named browser games are often confused. The table below separates them using the attribution and listing details that can be checked on their pages.
| Title | Who is credited | Listing details | Gameplay described |
|---|---|---|---|
| Hardest Game On Earth | MarketJS lists and licenses the game. No individual creator is named in the sources checked. | Released April 29, 2020 and last updated April 3, 2025, per the Coolmath Games listing. Browser and mobile platforms. | Single-player HTML5 maze game: navigate, collect coins and keys, avoid obstacles. On Coolmath, reach the yellow area while avoiding red enemies. |
| World’s Hardest Game | Developed by Snubby Land, according to Coolmath Games. | Uploaded to Coolmath Games in 2011. Release date and platforms not stated on the listing reviewed. | Not stated in the listing reviewed. |
Hardest Game On Earth: who made it
The MarketJS product page for Hardest Game On Earth presents the game as available for HTML5 licensing. It does not identify a person, studio, or author as the creator, and no named individual role or quotation appeared in the sources checked. Treat MarketJS as the listing and licensing provider, not as a confirmed developer, unless the page states otherwise.
That gap matters if you are writing a credit line. Without a named creator, the accurate phrasing is “available via MarketJS” rather than “created by” someone in particular.

Licensing terms on the listing
MarketJS lists a paid license at USD 999 for one project, end product, or client and one website or domain, with the game provided as-is. These are page-listed terms for the HTML5 version and can change, so check the product page before relying on them.
How the game is described
MarketJS describes a single-player maze game in which the player navigates the maze, collects coins and keys, and avoids obstacles. Coolmath Games lists the same title with tap-and-drag or keyboard controls, and tells players to reach the yellow area while avoiding red enemies. Those are catalog descriptions, not evidence about who built the game.

World’s Hardest Game: who made it
Coolmath Games credits World’s Hardest Game to Snubby Land and states that it was uploaded to Coolmath Games in 2011. Coolmath’s upload year is the platform’s own date, not a verified original release date, so it should not be presented as when the game first came out.
Why “hardest” is not a ranking
“The title says it all! This is the world’s hardest game” is marketing copy from the MarketJS listing. It is a claim by the seller, not an independent ranking or a test with a defined method. Neither listing gives a measurable difficulty score, player-survey result, or comparison that would let you call one game the hardest on earth. If you need a defensible statement, say which title you mean and what the listing says, rather than repeating the superlative as fact.

How to credit or license the right game
- Confirm the exact title. “Hardest Game On Earth” and “World’s Hardest Game” are different games with different attribution.
- For Hardest Game On Earth, cite the MarketJS listing for the license terms and describe the creator as not named there.
- For World’s Hardest Game, attribute the credit to Snubby Land as stated by Coolmath Games.
- Re-check prices and terms before publication or purchase, because listing terms change.
Attribution on a single listing can be incomplete or outdated. If the credit matters for a book, broadcast, or commercial project, ask the listing provider directly for the developer’s name and a written license.
Taken together, the two titles give two different answers. For Hardest Game On Earth, the verifiable answer is the MarketJS listing, with no individual named as creator. For World’s Hardest Game, the verifiable answer is Snubby Land, per Coolmath Games.
