Pixel Algo vs Dot.Entity

Pixel Algo brings Conway's Game of Life to your fingertips as a beautiful, interactive cellular automaton sandbox. Watch cells evolve, collide, and create emergent patterns — or take control and shape the grid yourself. FEATURES • Draw and erase cells with your finger • Place classic patterns: Glider, Pulsar, Gosper Gun, and more • Glass block and iridescent visual effects • Colony colors to track cell lineages • Cycle through color palettes automatically • Save and load grid snapshots • Adjustable simulation speed • Wrap-around or bounded edges • Auto-reset when the grid stagnates • Shake to clear the grid CONTROLS • 2-finger tap to pause/resume • Draw on the grid to create cells (when paused) • Double-tap to clear or randomize • Vertical drag to adjust speed • 3-finger tap to open the menu Pixel Algo is free with minimal, non-intrusive ads. Purchase Remove Ads once to enjoy an ad-free experience forever.

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.
