Unchanged-iguana

Collect 150 iguanas and keep your daily research going. In the refreshed Observatory, follow clues, complete tasks and decorate a lab of your own.

SIX CLUE-BASED CASES
Open three clues in each case and choose your answer. Replay any case. Your first completed case each day earns a research stamp.

THREE DAILY RESEARCH TASKS
Observe three times, try the daily quiz and open today's log to earn another stamp. A correct quiz answer also grants one free observation.

MAKE THE OBSERVATORY YOURS
Unlock eight decorations and three backgrounds with cumulative stamps; decorating does not spend them. Display collected favorites and pin your next goal from 15 collection themes.

A FAIR 150-SPECIMEN COLLECTION
Explore three archives with 50 iguanas each. Get five free observations daily. The base discovery chance is about 8%; your first discovery is guaranteed within four observations, followed by a variable 37–52-observation pity limit. New specimens are prioritized on discovery. Goals, decorations and ads never change the odds.

YOUR RECORDS STAY WITH YOU
No account is required. Core gameplay, the album and research work offline. Export and merge collection, research and decoration backups in Settings. Backups do not transfer observation credits. Korean, English and Japanese are supported.

A completed optional rewarded ad adds 10 observations, up to five times daily. Interstitial ads may appear after results and app-open ads on repeat launches. The Android version has no in-app purchases.
