A murder has been reported in Grimsborough, Detective. Grab your badge — the Chief is waiting. Criminal Case is the original hidden object detective game: the award-winning phenomenon that has turned more than 100 million players into detectives since 2012. Search crime scenes for clues, examine the evidence, interrogate the suspects — and when the proof is solid, arrest the killer yourself. INVESTIGATE CRIME SCENES Every case starts at the scene of the crime. Search gorgeous hand-drawn locations for hidden objects and vital clues, race the clock for the best score, and earn the stars that move your investigation forward. RUN THE LAB Take your findings to the forensics team. Analyze samples, decode messages, reconstruct torn documents and match fingerprints. In Grimsborough, every detail talks — if you know how to listen. INTERROGATE THE SUSPECTS Bring witnesses and suspects in for questioning. Compare their statements with the facts, catch them lying, and profile your killer trait by trait until only one name is left. ARREST THE KILLER Most mystery games end when you find the last object. Criminal Case is where it gets serious: match the evidence to your suspects and put the right one behind bars. Get it wrong, and a killer walks free. ONE CITY. 56 CASES. ONE CONSPIRACY. From the smokestacks of the Industrial Area to the runways of the Airport, the six districts of Grimsborough hide 56 murder cases — and the deeper you dig, the clearer it becomes that they are all connected.

Chromex trains two different color skills in one app. FIND THE ODD COLOR A grid of identical-looking tiles — except one. Find it and tap it. Score, and the grid grows while the color gap narrows. It starts at 2x2 and ends at 9x9, where the difference between right and wrong is a fraction of a shade. Four modes: • Time Attack — 60 seconds, find as many as you can • Survival — start with 10 seconds; correct answers buy time, mistakes burn it • Zen — no clock, no penalty • Extreme — razor-thin gaps, and one mistake ends the run Stuck on a hard level? Three hints per run widen the color gap without revealing the answer. RECALL THE COLOR A single color fills the screen. Memorize it. It disappears, and you rebuild it from memory using hue, saturation and brightness dials. Five rounds, ten points each, fifty in total. Three difficulties: • Easy — 5 seconds to memorize, unlimited time to answer • Hard — 3 seconds, 15 to answer, no hints • Brutal — 1.5 seconds, 7 to answer, near-identical tones DAILY CHALLENGE Everyone gets the same five colors each day. One official run, one score, and a streak to keep alive. PLAY WITH FRIENDS Send a friend the exact five colors you just played and see who scores higher. Or share your week and build a seven-day board together — no account, no sign-up, nothing leaves your phone. BUILT PROPERLY Colors are generated in perceptual color spaces (OKLCH and CIELAB), not raw RGB. That means difficulty stays honest across every hue: a hard level is equally hard in blue and in green. Your guesses are scored with CIEDE2000, the industry standard for measuring color difference. NO ACCOUNT, NO TRACKING Chromex collects nothing. There are no ads, no analytics, no servers. Your scores live on your device and nowhere else. Accessibility: color assist widens the gap, a color-blind-safe palette avoids red-green pairs, and Reduce Motion is respected. Sound and haptics can be switched off. Chromex is entertainment. It is not a medical or professional color vision test, and screens vary in how they reproduce color.

Verdict
The clearest difference is in-app purchases: Chromex at none against Criminal Case's 10. Chromex also leads on ads (none vs shown). Criminal Case's advantage is chart position (#132 vs unranked) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
