```auto
const COLS = 131;
const ROWS = 541;

```

= `212,613 pixels`

Re: pixels - the code uses cells (windows?) in 2x2 blocks with 1px gaps, giving only 3x131x541 = 212613. Not raw canvas pixels.

**Completion time ~2.64 days**

Max player windows: **19,018**

**Spoilers below for the completed tower appearance:**

| **Tower** | **Index range** | **Prime count** | **First prime** | **Last prime** |
| --- | --- | --- | --- | --- |
| Blade 1 | 1 – 70,871 | **7,016** | 2 | 70,867 |
| Blade 2 | 70,872 – 141,742 | **6,146** | 70,877 | 141,731 |
| Blade 3 | 141,743 – 212,613 | **5,856** | 141,761 | 212,593 |
| **Total** | **1 – 212,613** | **19,018** | 2 | 212,593 |

The very first window pixel (`index 1 = prime 2`) and the very last window pixel (`index 212,613 = prime 212,593`) are both white/player windows. The building is bookended by player windows.
