Rush Hour is the classic spot the difference stress test: a city street where almost everything repeats. Rows of identical windows, matching cars, evenly spaced lamp posts. Repetition defeats pattern recognition, because your brain has nothing unique to anchor on and quietly assumes that a grid it has already checked is unchanged. It usually is not.

What's in the scenes
Twelve street scenes with towers behind and traffic in front. Windows are drawn as regular grids, vehicles come in pairs of near-identical shapes, and street furniture is spaced at regular intervals. Differences are distributed across all three bands, so a solved upper third does not mean the rest is clean.
The difficulty curve across 12 levels
Levels 1 to 4 keep four differences and moderate density. From level 5 the window grids grow and a second vehicle pair enters the scene. The last four levels sit at five to six differences with the densest layouts in the pack, and moved objects appear in almost every one of them.
Typical solve time: A minute and a half is a good result in the early levels, two to three minutes at the end. This is the pack where hint usage rises most, and there is no shame in that.
Best suited to: Players who like methodical puzzles and want to train against repetition rather than clutter.
Solving tips for this pack
- Treat window grids as counts, not pictures: count lit windows per row and compare numbers.
- Check vehicles as pairs. If one car changed, its twin is the fastest reference you have.
- Sweep the pavement line last — it is narrow, and most players never look at it.
- Do not rush a second sweep of a band you already cleared; move on and come back with fresh eyes.
