“Open At Nine” begins with an intriguing premise that sets the tone for its audacious adventure. Imagine defeating a fearsome Demon God, only to inherit a dilapidated brothel and a devilishly seductive succubus. The narrative is a tantalizing twist of fate, where you’re tasked with not just managing a house of carnal delights but also navigating through a sea of debts and desires. It’s a story that boldly embraces its adult theme, crafting a provocative backdrop that’s as scandalous as it is captivating.
Straying from traditional simulation, “Open At Nine” delves into a more titillating territory, blending elements of puzzle battles and trading card dynamics. Each monster girl is a crucial chess piece in this game of sensual strategy, endowed with attributes like stamina, level, and a provocatively named ‘sex ability.’ Managing these attributes becomes a dance of delicate decisions, intertwining player wit with the game’s sultrier aspects.

The stamina system adds a layer of strategy – if depleted, your monster girls must rest or be revitalized with special items, injecting a sense of urgency into every choice. Leveling up increases stamina, intertwining growth with gameplay depth. The sex ability points, a euphemism for their erotic efficacy, dictate how effectively your girls can please clients, serving as a playful nod to the game’s steamy nature.
Each monster girl, from the enticing elves to the beguiling brownies, favors a specific room type, which not only enhances their abilities but also amplifies your earnings. This, combined with potions to boost their ‘lust,’ turns every decision into a potentially lucrative (and lascivious) one.

This game is not your typical brothel simulation; it’s a cunning game of amorous encounters and strategic maneuvering. While straightforward, this gameplay loop is addictively engaging, keeping you riveted as you unlock scintillating H-scenes that are as explicit as they are exquisitely animated.
The artistry in “Open At Nine” is where the game truly bares its soul. The illustrations are a sultry symphony of anime aesthetics, each monster girl a sensual sonnet of design and desire. These visual masterpieces aren’t just pleasing to the eye; they are the pulsating heart of the game, making every scene a feast for the senses.
While the soundtrack of “Open At Nine” weaves a whimsical anime ambiance, it’s the selective voice acting during the game’s H-scenes that really raises the temperature. The story scenes may not be voiced, but each monster girl has her own unique ‘voice’ – a symphony of suggestive phrases, moans, and cries that come to life in the raciest of moments. These sounds add a layer of intense realism to the game, enough to make even the most seasoned player blush. It’s this auditory artistry, albeit limited to the game’s more intimate scenes, that ensures you’ll be reaching for your headphones, not just for immersion, but also to keep the game’s sultry secrets between you and your screen.

“Open At Nine” embraces its adult content with unapologetic boldness. The game’s H-scenes are animated with a fervor and fidelity that are rare even in adult gaming. The range of monster girls ensures a variety of tantalizing encounters, each scene pushing boundaries and potentially turning cheeks as red as the game’s fiery passion.
Playing “Open At Nine” on devices like the ASUS ROG Ally or Steam Deck is a mixed experience. It’s evident the game was crafted with one-handed play in mind, yet the touch screen interface misses the mark in intuitiveness. A workaround is there, but it’s clear the game’s full seductive potential is best unleashed on a traditional PC setup.

For those brave enough to plunge into its steamy depths, “Open At Nine” promises a tantalizingly tumultuous journey.
