Math Gates vs Dot.Entity

Math Gates is a puzzle game where you build the machine instead of solving a worksheet. A bit carrying a number leaves the source and travels in a straight line. You place gates and mirrors on the board, then press Run. Gates change the number. Mirrors bend the path 90 degrees. The port at the end only accepts the value it asks for. Because the bit travels straight, the order it meets the gates is decided by where you put them. Want to add before you double? Then bend the path with a mirror and route it the other way. Function composition becomes a spatial design problem you can see. HOW IT PLAYS - Tap an empty cell, pick a gate or a mirror, and it drops into place - Every time you place a piece, the resulting path is drawn for you - You see whether it reaches the port before you ever press Run - Tap a placed piece again to swap it or take it back - No timers, no lives, no penalty for trying FEWER GATES, MORE STARS The tray always holds one more gate than you need. Reaching the port earns a star. Reaching it with the fewest gates earns three. There is always a shorter machine, and finding it is where the real thinking lives. 140 PUZZLES ACROSS 7 WORLDS - Adding and subtracting - Multiplying, dividing, and why order changes the answer - Remainders, odd and even - Negative numbers and flipping signs - Fractions and reciprocals - Squares and square roots - True, false, and logic gates 28 DISCOVERIES TO COLLECT Nothing is explained up front. You try, you watch, you notice. When you clear a puzzle, a card names what you just did and shows the formula behind it. Order matters. Two flips return you to the start. Doubling always gives an even number. The cards collect in a codex you can read any time. MADE TO BE READABLE Four shades of green, drawn like a handheld from 1989. No timers counting down, no popups, no clutter. Numbers and symbols carry the game, so it reads in any language. FREE, WITH A ONE-TIME OPTION Every puzzle is free. Ads appear between clears and never during play. A single purchase removes them for good. Built for ages 8 and up, and for any adult who likes a quiet puzzle.

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.
