Key highlight

BLACKBOX is a single-player trading sim where three playing cards drive market prices. Predict rises and falls, trade with BUY/SELL, and use poker hands and JOKER reversals to climb the ranks.

Who this is for

A fresh blend of card game and market simulation that offers quick, strategic sessions with surprising depth.

Details

Overview

BLACKBOX is a single-player trading simulation that turns the stock market into a card game. Developed and published by gohyaku, this indie strategy title launched on Steam on November 6, 2026.

You start with 100,000 CREDITS and must predict whether prices will rise or fall, then execute BUY and SELL orders to grow your wealth. The twist?

Three playing cards determine every market movement.

Highlights

Card-Driven Market: Positive and negative cards, poker hands, and a JOKER that reverses scores all influence price direction and magnitude.
Strategic Depth: A strong poker hand doesn't guarantee profit—the same combination can produce different outcomes depending on market conditions.
Accessible Controls: Supports keyboard-only or mouse-only play, with custom volume controls, making it easy to jump in.

Who It's For

If you enjoy resource management, score attack challenges, or poker-inspired strategy games, BLACKBOX offers a fresh take on trading. It's ideal for players who like to analyze patterns and make calculated risks, rather than relying on luck alone.

The game is currently available in Japanese, so a basic understanding of the language helps, though the core mechanics are intuitive enough to grasp quickly.
