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.

Dot.Entity You tap. Cells are born. They spread, collide, change shape — the way a short video captures mold growing or fruit decaying. That kind of quiet time-lapse, in your palm. Each cell becomes the seed of a structure no one can predict. Watch it unfold. --- [ What you can do ] ・1-minute tutorial covers the four B3/S23 rules ・Tap the board to drop random presets (Glider, Blinker, Block...). First 10 taps follow a curated sequence so motion is immediate ・47-entry Lexicon (23 still lifes, 20 oscillators, 4 spaceships) auto-populates as you discover patterns. Each entry carries its discovery year, discoverer, historical significance, and trivia ・COMBO mechanic — the longer motion sustains, the higher the counter climbs across 9 distinct tiers (color / sound / haptic). At the top tier the HUD pulses in rainbow ・Dramatic sessions auto-save to REPLAYS (combo peak ≥ 300). 16x time-lapse playback, Shannon entropy graphs, and automatic key- moment markers let you analyze past evolutions ・PLAYGROUND for designing your own patterns (up to 50 saved). EDIT supports finger-drag continuous drawing, each cell ringing a pentatonic note. 5 practice challenges (Block, Glider, R-pentomino, Acorn, Diehard) ・"Today's Challenge" — daily 8x8 puzzle, clear within 5 moves. Optional hints. 7-day sparkline with streak counter ・Share moments as text or image. Photo-library permission is requested ONLY if you choose "Save Image" from the share sheet ・Glossary with 35 English terms — still life, oscillator, spaceship, methuselah, Glider Gun, Universal Constructor, Moore neighborhood, chirality, puffer, Turing completeness, and more. 14+ terms include live preview animations. Daily-rotating trivia card ・26 achievements (Discovery 6 / COMBO 8 / Daily 7 / Meta 5). Stats panel + "Coming up" progress panel. 3 "hint-free clear" achievements give the Daily Challenge a self-best axis ・Daily streak counter with personal-best record --- [ Made for ] ・People who enjoy fast-motion videos of natural processes ・Anyone curious about Conway's Game of Life or cellular automata ・Fans of digital fidgeting and tactile interfaces ・Commutes, waiting rooms, winding down before bed --- [ Design principles ] Zero in-app purchases, ads, social features, or data collection. Fully offline. Sensory-friendly: haptic / audio / visual intensity each adjustable per-axis (off / soft / medium / strong). Auto-detects iOS Reduce Motion and Reduce Transparency. Full VoiceOver support. Predictable, low-stress: all rules in the 1-minute tutorial, no hidden mechanics, no failure states, no time limits. Daily Challenge hints are opt-in. Collection-first: 47-form Lexicon + 26 achievements make "collect them all" the primary axis. Instant tap reward — haptic + visual + audio fire together. --- [ About cellular automata ] Conway's Game of Life, announced by mathematician John Conway in 1970, is the most beloved cellular automaton in the world. From four simple neighbor-counting rules emerge spaceships, oscillators, glider guns, even Turing-complete computation. For over 50 years enthusiasts have discovered new patterns — Glider Gun (Gosper 1970), Pulsar (Conway 1971), Eater 1, Pentadecathlon, LWSS, MWSS, HWSS — all included here with their historical context.
