Sunshine hours count how long direct sunlight was strong enough to meet the meteorological sunshine threshold.

• This game uses total sunshine duration for calendar year 2025.
• Open-Meteo reports daily sunshine duration in seconds; the game sums those days into annual hours.
• The photo is a city clue. The answer is total 2025 sunshine hours for that city.

Sunshine duration is model-derived and grid-cell based, not a city hall weather-station receipt.
