About this game

Every system has a law. Rulebound is a compact deduction roguelite about finding it before your focus runs out.

Study the BOUND and BROKEN examples, build a four-token theory, and test it. A correct theory earns the resources you need for the next round. A failed theory costs a try, so every selection matters. Ask for up to three proof cases when you need more evidence, then decide for yourself.

Play through three escalating chapters and seven rounds, discover 40 deterministic law variants, practice eight standalone cases, and build a record through achievements and cumulative challenges. Rulebound is designed for short, replayable sessions and works without an account or an internet connection.

Features:
• Deduction runs with escalating puzzle difficulty
• Four-token theory building from visual signals
• BOUND and BROKEN examples with immediate feedback
• Proof cases instead of written solutions
• Three chapters and seven rounds per run
• 40 law variants and eight Practice Lab cases
• Achievements, challenges, rewards, and replayable runs
• Offline-first play with occasional interstitial ads between runs

Read carefully. Test boldly. Survive the system.
Read the signals. Find the hidden law. Survive a seven-round deduction run.
