Solve the 10x10 Skyscrapers puzzle below. Rules:
- Standard Skyscrapers rules: Insert a number from 1 through N into each cell in the N by N grid so that no number repeats in any row or column. Each number in the grid represents the height of a building, and each number on the outside of the grid represents the number of buildings that can be seen from that direction, where taller buildings block the view of smaller buildings behind them. (For this puzzle, N=10.)
- The three figures shaped like a capital II with serifs (in blue) are replicas. Cells in corresponding positions of replicas (without rotation or reflection) must contain identical numbers.
- Similarly, the two figures shaped like a capital II with no serifs (in purple) are replicas, and the two figures shaped like a lowercase ii (in orange) are replicas.
- The puzzle should be copy-pastable to a spreadsheet, or can be solved on Penpa with no letters here or with letters here. If you're using Penpa, the author recommends using Sudoku mode and using 0 to represent the number 10. (This message is not a puzzle.)
- Once you're done, take a look at the 2s and 4s.
This example uses a 4x4 grid and a different shape of replica.
