ABOUT THIS GAME

Crack the Code in 全部試せば開く!

In 全部試せば開く!, players are thrust into a world defined by curiosity and perseverance. A mysterious box awaits, locked with a code between 4 to 8 digits. The challenge is straightforward: your mission is to open it by trying every possible numeric combination up to 9999. No hints, no cryptic puzzles—just you and the numbers. Can your determination crack the code?

A Simple Yet Engaging Challenge

The gameplay revolves around pure mechanics. Players can manipulate the code using simple controls; clicking the ▲ and ▼ buttons adjusts the digits while arrow keys help navigate between them. Once you've settled on a guess, pressing Space, Enter, or clicking the treasure chest submits your input. It's a test of tenacity where every wrong answer only fuels the drive to succeed.

Skill Progression and Strategy

While players can tackle the challenge with raw determination, optional skills introduce a layer of strategy. Coins and gems sporadically drop during gameplay, which can be spent on skills that enhance efficiency. These skills offer minor advantages, but opting out of them can lead to greater rewards. Each skill purchase remains active until the player decides otherwise.

Difficulty Tailored to You

全部試せば開く! accommodates various skill levels with flexible difficulty options. Choose between codes of 4 to 8 digits, each having its dedicated save slot. Switching back and forth between these modes allows players to discover which one suits their style best while maintaining a single save file per difficulty level. Longer codes mean heftier rewards, intensifying the thrill of unlocking the box.

A Serious Mode for Hardcore Players

For those seeking an extra layer of challenge, the Serious Mode disables all skills, ramping up both difficulty and reward. This mode becomes a proving ground for players who thrive under pressure. Completing Serious Mode also counts toward achievements in Normal Mode, providing extra motivation for completionists to rise to the occasion.

Quick Tutorial to Get You Started

Concerned about the learning curve? Fear not, as a brief tutorial introduces the basic mechanics of the game. This condensed session features a 3-digit version of the box, allowing you to familiarize yourself with the controls and objectives in just a few minutes. It's a straightforward yet effective way to ease into the gameplay experience and start honing your code-cracking skills.

Stream and Share Your Journey

Another engaging aspect of 全部試せば開く! is the freedom players have to share their experiences. You can stream, record, and monetize content, whether you're creating Let's Plays, walkthroughs, or your own unique spin on the game. There are no restrictions on monetization methods, making it easier to connect with an audience while working through your numerical challenges. Invite your friends to witness your perseverance in action!
