Math Gates vs Gear combination

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.

Select a quest, and a rotating gear will appear in the upper left. Connect the gears on the right to the rotating gear to clear the quest. You can place gears freely in any position. Multiple quests are available, and you can play them in any order. Cleared quests can also be replayed as many times as you like. In this game, clockwise rotation is represented by positive numbers, and counterclockwise rotation is represented by negative numbers.
