| Reward | The King of QUB3D achievement |
QUB3D is the block puzzle machine you’ll spot in the corners of bars and shops around Liberty City. One run has to finish above 10,950, the high score shown at the top of the screen. Your name goes on the table, and the game gives you the King of QUB3D achievement. A good run can last ten minutes or more, so plan for one long sitting.

Where to find the machines
Homebrew Café
The Homebrew Café in Broker is the easiest place to start. The machine stands in the same room as the pool table, so you can play a game on both in one visit. Walk up to the cabinet and use the prompt that appears on screen.
Perestroika, back room
Perestroika is in Broker. The machine is in a back room, so head away from the main floor to find it.
Modo
Modo is the clothing store in Algonquin. You’ll find the cabinet inside, so it’s a handy stop when you’re already shopping.
The Triangle Club
The Triangle Club is in Northern Gardens, Bohan. You’ll find the cabinet inside. Every machine plays the same game and records to the same high score table, so pick whichever is closest to where you’re driving.
How QUB3D works
Blocks fall in pairs onto a grid. Line up four or more of the same color to clear them. A new level arrives as your score climbs, and the blocks fall faster each time. You start with blue, green and red blocks. Yellow joins at level 5, purple at level 10 and orange at level 15, so the board gets harder to read as you go.
Build a two-by-two square of one color and it adds to your Power bar without clearing the blocks next to it. Fill the bar with four squares and you can pick a special. The red special wipes the bottom four rows. The green one clears the two middle columns. The blue one removes every block of a color you choose, and the yellow one holds the falling blocks in place so you can steer them down yourself. You can store three specials at a time, so don’t waste them early.
Beating 10,950
The first minutes are easy, and the score is in the low thousands by level 12. Clear small groups and build squares while the board has room. Keep the middle columns lower than the edges, so new pairs always have somewhere to drop. Save your specials for a crowded board, not an empty one.
Past level 15 all six colors are in play and the stack fills fast. Keep using your specials to clear space, and the score gets past 10,950 somewhere in the high teens of levels, depending on how you play. Your total shows in the top corner the whole time, so you know how close you are. Keep playing past the line for a cushion. The game asks for your initials when the run ends.
King of QUB3D
The achievement pops as soon as your final score tops the old best and you enter your initials. Once you’ve done it, you’re finished with QUB3D for 100%. Head back to pool, darts and bowling for the other game wins, or browse the achievements page and Optional activities.
