FULL (up-to-date) CHANGELOG: In-game settings -> scroll near the bottom, [What's New / Changelog]! (NULLBYTE Watch info on bottom of this)
// if you start playing today: 30.6.2026, you'll get the full rewards from the new monthly login system!
-- -- -- -- -- -- -- -- -- -- -- -- -- --
Now also available for Android TV! Please keep in mind: the Android TV version of NULLBYTE is not a 1:1 replica of the original and is not intended to replace the main version.

NULLBYTE is designed & built to be played in portrait mode. When you switch to landscape, some, none, or all elements may break. If "things" look odd, rotate back to portrait!

You are an operator on the NULLBYTE network.
Your terminal is your weapon. Every player on the network has an IP address, a reputation, and something worth stealing. Scan them. Crack their defenses. Raid their vault. Or get raided yourself.
NULLBYTE is a competitive hacker simulation where every raid target is a real player. Every intrusion you launch hits someone's actual account — and every alert you receive means someone is coming for yours. Learn the ropes through missions, then take on the network.
— CRACK CIPHERS —
The core skill. ROT13, Vigenère, Affine, Rail Fence, Playfair, XOR, Substitution — over a dozen cipher methods stand between you and your target's data. Decode them fast under a trace timer, or get locked out.
— SCAN & RAID —
Every operator has an IP. Scan it to assess their defenses before committing to a raid. Successful intrusions steal BTC from the target and boost your reputation. Failed ones cost you.
— DAILY CIPHER —
A new challenge every day. Crack it for bonus BTC and streak rewards. Tiered hints help when you're stuck — but using them costs you.
— BUILD A CREW —
Recruit up to 10 operators into a crew. Pool resources, coordinate mega-raids on hardened targets, and climb the crew leaderboard together. Strength in numbers.
— CLIMB THE LADDER —
Global leaderboards track BTC holdings, reputation, daily cipher streaks, and raid stats. Your handle and badge are visible to everyone. Make a name or become a target.
— YOUR IDENTITY —
Your IP address is your callsign. Other operators can scan it, track it, and hit it. Swap to a recycled address with reputation — or purchase a fresh IP that's never been assigned.
— TERMINAL AESTHETIC —
No flashy 3D graphics. NULLBYTE runs in a terminal interface — green on black, monospace type, command-line feel.
Free to play. Optional in-app purchases for supporting the developer. Contains ads.
Hack the network. Own the ladder. Don't get caught.
----------NULLBYTE for Wear OS runs your Hot Wallet----------
Your wrist is now a mining rig. NULLBYTE for Wear OS runs your Hot Wallet
straight from the watch: the auto-miner ramps up on its own, BTC piles up,
and you cash out to your phone with one tap. See your rate, the fill meter,
and the countdown to the next hack. Claim requires Ghost OS or the Hot Wallet unlock in the phone app (Legacy UI).
COMPANION FOR YOUR WRIST
The NULLBYTE watch app is your Hot Wallet's mining rig. It runs on its own:
the miner's rate ramps up over time, BTC accrues into the wallet up to its
cap, and a single tap claims the whole balance to your phone — where it
becomes usable BTC.
What you see on the watch:
• Live Hot Wallet balance and mining rate
• Fill meter — how close the wallet is to its cap
• "Next hack" countdown to the next ramp step
• One-tap CLAIM to send everything to your phone
The watch is a free companion — it shows and accrues for anyone. Claiming to your phone requires Ghost OS or the Hot Wallet unlock, bought once in the
phone app. No subscriptions.
Requires the NULLBYTE phone app (signs you in; the watch relays that login).
