Raise two towers, predict a diagonal sky bridge's length, then build it.

Two towers. A long walk around the block. Or one daring sky bridge straight across. How long will it be?

What you’ll build

Raise two towers at the same height, then use a famous maths hack to predict how long a diagonal sky bridge between them will be before you place a block. Build it as smooth repeating steps, dress it with glass or rails, then race the street route against your shortcut.

Finish line: Your two towers are joined by a diagonal sky bridge whose length you predicted and then checked.

Bonus challenge: Add a second sky bridge from a third tower. Predict the X and Z where the two bridges cross, then fly there and check.

You’ll need

  • Tower blocks
  • Glass or rails for the bridge
  • A calculator with √

You choose

  • My towers stand at: ____________ and
  • Bridge width (3 or 5) and style (glass, rails…)
  • My step ratio (1:1, 1:2 or 3:4)

Stuck?

  • Bridge looks jagged? Keep the same step pattern all the way across, such as 3 along X then 4 along Z, and repeat.
  • Answer won't come out whole? Pick tower gaps in a 3:4 ratio, like 60 and 80 blocks, for a neat 100.
  • Measure the X and Z gaps from the same point on each tower, like a matching corner, so a and b are accurate.
