About This Game

Welcome to No. 9 Pool Hall

On a rainy street after dark, an old neon sign flickers to life.

No. 9 Pool Hall: Heartbeat Partners is a casual game that combines playable pool, character-driven stories, roguelike score-building, and matches with friends. Practice your shots, meet partners with distinct personalities and playing styles, and gradually discover their stories through games and conversations.

Play a Real Game of Pool

Aim and charge each shot with the mouse, predict the cue ball’s path, and manage solids, stripes, fouls, ball-in-hand situations, and the final eight ball.

Every decision matters, from basic shot-making and power control to position play and extended runs. Each partner has a different approach, level of accuracy, and response to the table, requiring you to adapt your strategy throughout the match.

Survive Nine Strange Nights

Night Voyage is a nine-night roguelike scoring challenge that transforms the familiar pool table into a growing collection of unusual effects.

Collect special balls that modify base scores, pocket multipliers, and multiplicative bonuses. Between nights, visit the shop to purchase new balls, combine matching effects, manage storage, and rearrange the opening formation for your next game.

Target valuable pockets, create scoring chains, develop balls that grow stronger over time, or build an entire strategy around a particular effect. As the required score rises each night, the table gradually becomes a unique build shaped by your choices.

Meet the Partners of the Night

Every partner at No. 9 Pool Hall has a distinct profile, personality, playing style, and personal story.

Important shots, successful runs, and unexpected mistakes can lead to different reactions. Build rapport through matches and conversations, unlock character chapters, make choices during key moments, and collect keepsakes that preserve the memories you create together.

Winning is not the only thing that matters here. Every game can be the beginning of getting to know someone.

Practice Alone or Invite a Friend

Learn aiming, power control, and cue-ball positioning through dedicated practice challenges. Face computer-controlled opponents at different difficulty levels, or invite a Steam friend to a two-player match.
