You are a part-time detective who helps out Inspector Thadeus Deprehensio, from the local office, who you affectionately call "Inspector Thad." Together, you will help solve countless cases, some easier than others, some challenging, which will keep your wits sharp, your mind logical, and the world a better place. If you need assistance, just tap the Help button which will reveal all--including the ability to shake this device to start over or to clear your notes grid. In this free Lite version, select from 4 cases of varying difficulty. Tapping on a case brings you to the main grid. Here, you'll see scrollable text that talks about the case and gives clues you'll need. Based on these clues, you can circle and cross out possible suspects. Based on the clues and your grid notes, you enter your hypotheses in the Answer page where clicking on 'Check' lets you see if your answers are correct so far--letting you correct what you've missed. Your changes are always saved! Should you decide to leave the current case unfinished because you want to work on another case, your answers as well as your grid notes are all saved so you can go back to work on them again at a later time. So what are you waiting for, my dear detective? Get out your magnifying glass, your fingerprint kit and download this app now! The game's afoot! Update: want more puzzles? iDetective is now available on the iTunes app store with 32 puzzles! With more to come as free updates!

Place blocks, clear lines. Gems multiply your score. Collect and upgrade them. That third line is what makes Gemz different from other block puzzles. THE BOARD Drop pieces onto an 8x8 grid and complete a row or a column to clear it. Nothing falls on its own, nothing is timed. Every move is yours to think about. GEMS ARE THE SCORE A line carrying gems is worth far more than an empty one, and clearing several lines in one move multiplies it again. Keep clearing on consecutive moves and the combo climbs. Every scoring move also fills the golden frame around the board: once it is full, your next move is worth ×10. The huge scores come from setting them up, not from luck. THE COLLECTION IS YOUR BUILD Dozens of stones to find across eight rarities, from common rock crystal to Martian meteorite. Duplicates raise a gem's level, and enough levels change its shape: rough, then polished, then faceted. Every shape is a different 3D stone, and a bigger multiplier. Only the gems you carry fall on your board. Your mix starts at three slots and widens as you rank up, so choosing what to bring is the real decision. ALSO INSIDE - 200 handmade levels with up to 5 stars each, then the Champion's League - A weekly tournament across five divisions, Rookie to Elite - The Events page: a challenge of the day and monthly events, each with its own rewards - The Meteor Shower, one weekend a month: meteorites crash onto your board, and you crack them open for rare gems - Daily missions, chests to open, and a shop that turns over every day - Plays offline, in portrait, one-handed Free to play.

Verdict
The clearest difference is in-app purchases: iDetectiveLt Logic Puzzles at none against Gemz!'s 7. iDetectiveLt Logic Puzzles also leads on ads (none vs shown). Gemz!'s advantage is update cadence (every 3 days vs every 11 months) and iOS requirement (15.0 vs 17.4). On price and device support there is nothing between them.
