Tower Stack is a free tower building game inspired by Tower Bloxx, the crane game many of us first played on an old Nokia. A floor swings from the crane, you drop it at the right moment, and the building grows one storey at a time. Pick a famous landmark like Minar-e-Pakistan or the Burj Khalifa and try to build higher.
Each new floor hangs from a crane and swings left and right like a pendulum. Tap the screen, click, or press Space when you think it is lined up with the floor below, and it drops straight down onto your tower.
If it lands well, the floor stays and new residents move in. If it lands too far off to one side, it tips over the edge and falls. If it misses the tower completely, it falls to the street. Either way you lose one of your three hearts.
The game is all about timing and reading the movement. The swing gets a little faster and a little wider as the tower rises, and a tall tower rocks more than a short one.
On a computer, press Space or Enter to drop the floor, or click anywhere on the game. Press P or Esc to pause.
On a phone or tablet, tap anywhere on the screen to drop. One finger is all you need, which makes it easy to play with one hand on the bus or in a queue.
Your score in Tower Stack is the number of residents living in your building. Every floor that stays on the tower brings in a few new people, and floors higher up bring in a bit more.
A Perfect is a drop that lands almost dead centre on the floor below. The game snaps it neatly into place, adds 8 bonus residents, and calms some of the tower's rocking. Land Perfects one after another and you build a combo. The second Perfect in a row is worth 1.25 times as much, the third 1.5 times, and so on up to 3 times. A drop that is not a Perfect, or a lost heart, resets the combo.
A floor stays on the tower as long as at least about a third of it rests on the floor below. Anything less and it slips off.
Before you start, you choose what to build against. Each landmark has a target number of floors. Reach it and you beat that landmark, with fireworks, and then you can keep stacking to see how far above it you can go. Free build has no target, just height.
- Leaning Tower of Pisa: 8 floors (Easy)
- Minar-e-Pakistan, Lahore: 10 floors (Easy)
- Big Ben: 13 floors (Easy)
- Eiffel Tower: 20 floors (Medium)
- Empire State Building: 28 floors (Medium)
- Petronas Towers: 32 floors (Hard)
- Taipei 101: 38 floors (Hard)
- Shanghai Tower: 45 floors (Very hard)
- Burj Khalifa: 55 floors (Legendary)
The floor keeps a little of its sideways speed when you let go. If you release it exactly as it passes over the tower, it will drift slightly past the centre. Release a touch early instead, just before it reaches the middle.
Off-centre landings shove the tower sideways and make it sway, and an uneven stack leans towards its heavy side. A swaying top means you are aiming at a moving target. Watch where the top floor is heading and time your drop for where it will be when the floor arrives.
- Go for Perfects early, while the swing is slow. They calm the tower and build your combo.
- If the tower is rocking hard, wait a swing or two for it to settle before you drop.
- After a sloppy drop, focus on a safe landing next rather than a risky Perfect.
- Your third heart is your last. Play it safe and steady when you are down to one.
You have three hearts. Each floor that slips off the edge or misses the tower costs one. When the third one is gone, the building closes and the game shows your floors, residents, Perfects and best combo.
Your best height and best residents are saved in your browser, along with your best result for each landmark, so you can see which ones you have beaten next time you play on the same device.
Tower Bloxx was released by Digital Chocolate in 2005 for Java mobile phones and became a favourite on Nokia handsets across Pakistan, India and beyond. The idea was simple: swing, drop, stack. Tower Stack is an original PlayNest game built on that same one-tap feel, with landmark challenges, a day and night sky and a couple of chatty characters, Rival Raza and Coach Sana, cheering and teasing you along. It is not affiliated with Tower Bloxx or Digital Chocolate.
