Unchanged-iguana

The iguana looks exactly the same. Everything around it is suspicious. Observe, inspect clues and record the wonderfully uneventful truth.

MORE WAYS TO OBSERVE
Receive 10 daily observations and earn extra credits from research tasks and experiments. Earned banked credits do not expire. Daily credits reset at midnight Korean time and unused daily allowances do not accumulate.

THREE OBSERVATION GAMES
Spot what changed behind the shutter, rebuild a curious sequence, and identify real traces from silhouettes, cropped details and behavior. Explore 36 authored puzzles, with three daily reward puzzles, free hints, retries and unlimited practice.

EXPLORE WHILE AWAY
Send one to three collected iguanas to three expedition regions. Reports arrive after four hours and wait until you collect them. Receive a report reward once a day and discover 30 expedition iguanas in a fixed regional order. These 30 are guaranteed expedition discoveries, separate from the original 150 random observations.

A LIFE BEYOND THE ALBUM
Investigate 24 cases, unlock 12 companion stories and complete 21 themed collections. Decorate with 24 props and 6 backgrounds. Save three named displays, take in-game photos and optionally share them through your device.

Core play and expeditions work offline. Advertising requires an internet connection. Optional rewarded ads grant 10 observations, up to five times a day. Interstitial ads may follow results and app-open ads may appear on repeat launches. The Android version has no in-app purchases.

Collection backups merge discoveries and research; they do not restore credit balances or active expeditions. Play in Korean, English, Japanese or Traditional Chinese, with Hong Kong and Taiwan wording.
