Clue Formula is a 3D Mahjong puzzle with IQ-test style tiles and pattern-matching challenges. Your goal is to complete all levels. In each level, remove all tiles by selecting matching pairs. Not every matching tile can be selected. A tile is selectable only when it is positioned at the end of a row - when there is no neighboring tile on at least one side (left or right) within the same layer. To complete a level, you need to find matching pairs where both tiles are selectable. Each new level becomes more challenging as you advance. A hint can show all selectable matching pairs. A shuffle can rearrange the remaining tiles and help you continue the level. Key Features: 3D Mahjong Puzzle: Match selectable pairs and clear each level. IQ-Test Style Tiles: Match tiles using shapes and symbols. Layered 3D Levels: Look through rows and layers to find selectable matching pairs. Leaderboards: Complete levels and compete for a place on the leaderboards. Accessibility and Device Support: Clue Formula is fully playable with VoiceOver. Clue Formula is fully supported on Mac. Extra hints and extra shuffles are available for purchase.

People say looks don't matter. People are wrong. Monster Set Go! is the classic card game Set, reborn with adorable monsters. Same beautiful brain-bending logic. Zero beige cardboard. The rule is simple. Find three monsters where every visual attribute (color, pattern, eyes, form) is either THE SAME across all three, or DIFFERENT across all three. That's it. That's the whole rule. Your brain will still argue with you about it. *** WHY MONSTERS INSTEAD OF CARDS *** Set has been a cult classic for decades: the purest pattern-recognition puzzle ever printed. We kept the mechanic exactly as clever as it always was, then handed it to a cast of hand-drawn monsters who blink, wiggle, and celebrate every time you spot one. Same workout for your brain. Considerably more charm. *** THREE WAYS TO PLAY *** CLASSIC: Chill set-spotting satisfaction. Solve at your own pace, or race the clock to earn every star. TIMED: The clock is not your friend. Spot sets fast, before it runs out. REFILL: New monsters keep dropping in from above. Clear sets or get buried. Endless, if you're quick enough. *** CAMPAIGN: 100 LEVELS *** Start with two attributes and a small board. Finish somewhere you didn't think your brain could go. New attributes unlock as you climb, boards grow, and the sets get sneakier. Clearing all 100 levels is one thing. Clearing them fast enough to collect every star is another thing entirely. *** QUICK GAME *** Randomized boards in any mode, at any difficulty you've unlocked. Perfect for a two-minute break, a waiting room, or a commute. Climb the leaderboards if you think you're fast. *** GOOD TO KNOW *** Is this like the card game Set? Yes. It's the same core rule, every attribute all-same or all-different, with monsters instead of shapes, plus Timed and Refill modes the cardboard version never had. Do I need to know Set already? No. Level 1 teaches you in about ten seconds. Is it good for kids? Yes. Pure logic, no violence, no chat, nothing scary. Is it hard? It starts gentle and ends brutal. That's the point. Do I need wifi? No. Monster Set Go! plays offline. Plane, subway, basement, wherever. Is it free? Yes. One optional In-App Purchase removes ads. Nothing else to buy, ever. Adorable monsters. One elegant rule. A hundred levels of "wait, THAT was a set?" Enjoy!
