Grimace's Birthday: A Unique Promotional Browser Video Game

Grimace's Birthday is a captivating online browser video game released in 2023. Developed by Krool Toys and published by McDonald's, the game was intended as a promotional venture. The developers crafted an action-packed platformer, reminiscent of Game Boy Color titles, using sophisticated software to bring the nostalgic gaming experience to modern players. Although Grimace's Birthday was not officially licensed by Nintendo as a Game Boy game, its files are fully compatible with Game Boy hardware. Upon its release, the game garnered positive reception, surprising critics with its unexpected theme and medium for a promotional game, and impressing players with its striking resemblance to classic Game Boy titles.

Gameplay Overview:

Grimace's Birthday offers players a side-scrolling platformer experience, where they assume the role of the beloved Grimace character through four engaging levels spread across two stages. The gameplay begins in the first stage with Grimace riding a skateboard, enabling players to perform rail grinds and tricks. The second stage allows Grimace to move freely and grants a bubble power-up, allowing players to float through certain obstacles. Each level is subjected to a time limit, and players earn points based on their accomplishments, such as defeating enemies and executing tricks skillfully. Throughout the levels, players can collect 40 Grimace Shakes, which grant additional points and add to the game's excitement. After completing the stages, players can indulge in a bonus minigame and blow out the candles on their birthday cake, further boosting their score.

Game Modes and Challenges:

Grimace's Birthday presents players with two distinct game modes, catering to different playstyles and levels of competitiveness. The primary mode is the engaging 'Story Mode,' where players embark on an adventurous journey with Grimace, completing challenges and unlocking exciting new elements. Alternatively, players can choose the adrenaline-pumping 'Score Attack' mode, wherein they must strive to amass as many points as possible within a limited timeframe. For those who prefer a more leisurely approach, the 'Freeskate' mode allows players to explore the game's environments freely without any time constraints.

Difficulty Levels and Skill Mastery:

To accommodate players of varying skill levels, Grimace's Birthday includes two difficulty settings. The 'Normal Mode' provides a balanced and enjoyable experience for most players, while the more daring and experienced gamers can opt for the 'Hard Mode.' In this challenging mode, the auto-grind feature is removed, demanding more precise control and skillful execution of tricks, resulting in double the points for each successful maneuver. This adds an extra layer of excitement for seasoned players seeking a true test of their platforming prowess.


Grimace's Birthday stands as an extraordinary example of a promotional video game, expertly blending nostalgia with modern gaming mechanics. With its endearing protagonist, captivating gameplay, and nods to classic Game Boy titles, the game successfully captured the hearts of players and critics alike. By offering diverse game modes and difficulty levels, Grimace's Birthday managed to appeal to a broad audience, catering to both casual and hardcore gamers. As players celebrated Grimace's virtual birthday, they were treated to an unforgettable gaming experience, reaffirming the potency of imaginative and well-executed promotional games.
