About

NAND

Read full description

NAND is a simple puzzle game with six levels and no timer. Using bitwise operators and arrow keys, try to reach the goal at the top in the fewest moves! It will be difficult for beginners and people unfamiliar with bitwise operators, but you can improve with practice and understanding!

About

Dot.Entity

Read full description

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.

Verdict

The call

NAND and Dot.Entity are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
