Hub 4 is a weekly treasure hunt played on the streets of Melbourne. You solve a clue, find a hidden sticker, answer a skill question, and the cash is yours. It's that simple. Membership costs $25 per month. You can cancel any time. The next hunt kicks off on 15 August 2026. This isn't a lottery. You earn the prize.

The Hunt Starts Here: Your Weekly Clue

Every week, a new clue lands in your membership portal. This isn't some generic riddle. Your clue is written for you personally by AI. The wording changes, but the information stays the same. Nobody gets an advantage, and there's nothing to copy off anyone else. Your job is to crack it. This means looking at Melbourne differently. It might lead you to a specific landmark in Fitzroy. Perhaps a lesser-known plaque in Carlton. Or a particular piece of street art in Collingwood. It rewards local knowledge. It rewards paying attention to the details of the city around you. You're looking for a specific spot, tucked away. It's a mental workout. You're piecing together fragments, connecting them to real-world locations. The city is the board. You need to know its odd corners.

Sharpening the Focus

As you get closer to the token, the game gives you more help. This isn't a handout. You earn it by being there. Get within 400 metres of the hidden sticker, and a second clue unlocks. This one describes what you'd see from across the street. It narrows things down. Push closer, get within 120 metres, and a third clue appears. This final clue tells you almost exactly where the sticker is. It's precise. You won't find these extra details on your couch. You have to walk. You have to be in the zone, physically present in that part of Melbourne. It’s a proper Melbourne scavenger hunt.

On the Ground: Finding the Token

So, you've solved the clues, and you're in the right area. What next? You're looking for a physical Hub 4 sticker. It's about the size of a drink coaster. It will be stuck somewhere. It won't be out in the open, but it won't be impossible to find. Think subtle. Think hidden in plain sight. Once you spot it, your next move is critical. You need to photograph it exactly where it is. Do not move it. Do not peel it off. Leave it there for whoever comes next.

The Proof is in Your Feet

Your claim only counts if you are physically at the sticker. Your phone's GPS needs to put you within 75 metres of it. We also need to see that your photo matches the location. This is non-negotiable. No exceptions. This means nobody wins from their desk. You have to put in the legwork. You have to be there. Location access is required to play Hub 4. It's how we verify your find. The hunt map shows you how close you are, but it never shows your exact position. We store the distance, not your precise coordinates. This keeps things fair. What if someone else gets there first? The sticker stays put. Even after a hunt is won, if you find that sticker later in the week and pass the location and photo checks, you still earn 50 skill points. The walk is never wasted. The city remains worth exploring.

Winning the Prize: The Final Test

Finding the token is a huge step. But it's not the win. Not yet. The moment your find is verified, a 15-minute exclusive window opens. This time belongs to you alone. Nobody else can claim the token during these 15 minutes. During this window, you face the skill question. Answer it correctly, and the cash prize is yours. This is where the pressure comes in. You've walked, you've solved, you've found. Now you need to think. This makes Hub 4 a true cash prize treasure hunt. What if you get the skill question wrong? You get a five-minute cooldown. While that's burning down, your 15-minute window keeps ticking. If your window runs out before you get the question right, the question opens up to every other member. The race is properly on again. Being first to the spot is a real advantage, but it's never a guarantee. The prize goes to whoever can perform under pressure. Winners are paid within 48 hours.

Fair Play, Real Skill

Hub 4 isn't gambling. There's no random draw, no chance element. Every win is solved, found, and answered. It’s a game of skill. We built it this way from scratch because fair play matters when real money is involved. You compete at your own level. Consistent winners are promoted to a higher skill league. This means harder clues, and it leaves the entry division open for newer members. Everyone gets a shot. Anyone 18 or over can join, provided you can get around Melbourne. We verify one account per person via SMS. This keeps the game honest and ensures fair competition. Hub 4 is owned and operated by Synap AI Pty Ltd (ABN 86 695 003 653 · ACN 695 003 653). Want to bring a mate along? Every member gets a personal invite link. If someone joins through your link, you earn 10% of their membership fee. For as long as they stay a member, that 10% comes straight off your own monthly bill. It pays you back. It also makes the prizes bigger, as the prize pool is funded by memberships. More members mean more money to be found.

Exploring Melbourne: Beyond the Prize

Hub 4 is more than just a hunt for cash. It's a reason to explore Melbourne. Tokens are hidden across zones spanning the whole city. North, east, bayside, west. This means wins spread across the map. It's not just whoever lives closest to the CBD. You'll discover new laneways, hidden parks, and bits of the city you never knew existed. It's about getting out there. Walking the city. Seeing it with new eyes. Many members find it a great way to discover new parts of their city on a weekend. It's an outdoor activity for adults that takes you off the usual tourist track and into the real Melbourne. You can find out more about what the City of Melbourne has to offer on their official website. For broader information about Victoria's capital, Wikipedia's Melbourne page is a good resource. You might even find some inspiration for your next hunt. The hunt takes you places. Maybe you'll find yourself searching for a hint near the Yarra River, or deciphering a clue pointing to a forgotten piece of history in Southbank.

Somewhere out there, a token is waiting.

Hub 4 is a straightforward proposition. A weekly challenge. A real cash prize. Melbourne as your playground. It’s about skill, local knowledge, and putting in the effort. The next hunt starts 15 August 2026. Join the club at hub4.au.
