Stealing The Diamond

What is Stealing the Diamond?

Stealing the Diamond is the third game in the Henry Stickmin series, tasking the loveable stickman thief with an ambitious heist: stealing the world's largest diamond from the National Museum of History and Culture. The museum is heavily guarded, the diamond is heavily secured, and Henry's chosen approach is an eclectic menu of increasingly absurd methods that range from tunnelling in with heavy equipment to arriving through the front door in an elaborate disguise. As with all Henry Stickmin games, the failures are often funnier than the successes, and discovering all the comedic animations is as rewarding as completing the heist.

How to Play Stealing the Diamond

At key decision points throughout the heist, the game presents you with a menu of action choices - typically three options at major junctions, each representing a wildly different approach. Selecting an option plays an animated sequence showing the outcome. Successful choices advance the heist. Failed choices - which are most of them on a first playthrough - play a comedic failure animation before returning you to the choice screen. The game has multiple successful paths that represent genuinely different heist approaches, each with their own sequence of decisions and unique animations. Finding every path and every failure animation is the completionist goal that rewards thorough investigation.

The Heist Approaches

Stealing the Diamond offers two distinct successful heist paths that involve fundamentally different strategies. The stealthy approach requires Henry to infiltrate the museum without alerting security, navigating through the building while making choices that keep him undetected. The aggressive approach involves a more direct assault on the museum's defences, using heavy-handed methods that generate chaos but eventually deliver the diamond. Each path has its own sequence of choices, failure animations, and a distinct ending that reflects the method used. Completing both paths provides a substantially fuller picture of the game's content.

Comedy Writing and Cultural References

The Henry Stickmin series is built on a specific style of comedy: placing its stickman protagonist in situations drawn from action movie conventions and then demonstrating with great enthusiasm exactly why each conventional approach fails in practice. Stealing the Diamond expands this with a heist-movie framework that allows the game to parody a particularly rich genre. The failure animations reference films, video games, and internet culture in ways that reward players who recognise the references while remaining funny through the quality of the animation even for those who miss them.

Connection to the Henry Stickmin Series

Stealing the Diamond sits in the middle of the Henry Stickmin series' chronology, following Escaping the Prison and preceding Infiltrating the Airship. The choices made in earlier games can affect options available in later entries when playing through the complete Completing the Mission collection, making each individual game a standalone experience that also serves as a chapter in a larger narrative. Stealing the Diamond establishes Henry's reputation and connections that matter in the games that follow.

Why Stealing the Diamond is a Fan Favourite

The museum setting provides a richer environment for heist comedy than earlier Henry Stickmin games, and the expanded choice menus give the failure animation content a density that rewards systematic investigation. The two successful path structure adds replay value beyond the initial discovery session, and the quality of the animation throughout makes even repeated viewings of favourite failure moments worthwhile.
