Binar.io vs Gate Master

Binar.io is an assembly language puzzle game. You are given a machine, a specification, and a blank page. The BN-8 is an 8-bit processor with two registers, a loop counter, two flags, and twenty-seven instructions. It has no multiplier, no divider, and no compare instruction. Everything it can do, you build out of what it has. HOW IT WORKS Each level states a function, not a number. "Return the input with its two nibbles exchanged." "Return 1 when an odd number of the input's bits are set." A byte arrives in register A; whatever is in A when your listing ends is your answer. Your program is checked against cases you can see and cases you cannot. So there is nothing to write down and nothing to look up. The program has to be right for inputs you were never shown. THREE KINDS OF PUZZLE BUILD gives you a blank page and a contract. REPAIR gives you a listing that is already wrong, and a fault report. The first level in the game is one of these, and the program it hands you passes its first test case on purpose. IDENTIFY gives you nothing but the cases. Working out what the part is supposed to do is the puzzle. THREE SCORES, NOT ONE Every solution is measured on instructions, cycles, and silicon cost. On the levels that matter these do not agree: the smallest program and the cheapest program are different programs, and you cannot have both. A working program is always worth a star. Optimising is the reason to come back to a level, never the price of leaving it. WHAT IS IN IT 48 specifications across four worlds, from a single shift to bit reversal, packed field extraction, the doubling ladder, and a fourth world of memory, stacks and subroutines. A warm-up mode with 72 generated levels, each with a proven shortest solution. A one-page instruction reference you can open at any time. Dry and technical on purpose. No story, no energy timers, no ads, no subscription. World 1 is free, with all twelve specifications. The existing Full Campaign Unlock is an optional one-time purchase for the rest of the campaign. The App Store shows the price. For anyone who likes TIS-100, Shenzhen I/O, or finding out that the thing they built by hand was a single opcode all along.

The town has lost its power! The lamps are dark, the bank vault is locked, and the traffic lights have gone out. Travel from region to region with your guide Wire, fix the circuits and bring the town's lights back on. Gate Master is a puzzle game played with real logic gates. Every level shows a real device at the top of the screen: a night light, a doorbell, an elevator, a traffic light. Below it sits the circuit board. Drop the right gate into each empty slot, press Test and watch whether the device works in every case. MEET THE GATES Every gate has a face and a personality: AND with its glasses, OR with its little sprout, NOT who flips everything around, NAND in a cape, XOR with a crown... When their output is 1 their faces light up, and at 0 they doze off. Each new gate arrives with its own intro card. BUILD, PREDICT, FIND THE FAULT Levels don't always ask for the same thing: • Build: place gates in the slots, and sometimes choose where a wire goes • Predict: look at the circuit. Will the lamp turn on or stay off? • Set the switches: flip the inputs to reach the goal • Find the fault: spot the wrong gate and swap it • Only these gates: copy one gate using just one kind of gate • Machine: a big circuit at the end of every region 10 REGIONS, 200 LEVELS Home, Bank, Apartment, Greenhouse, Factory, Stairs, Workshop, School, Traffic and Clock Tower. You start with a single wire and a NOT gate. After AND, OR, NAND, NOR, XOR and XNOR come binary numbers, adders, a 7-segment display, selectors, decoders and, at the very end, memory and counters. The challenge grows step by step, and every level was checked to be solvable. TEST IT, WATCH THE LIST The Test button tries every input combination in turn, filling the list of tries row by row. You see exactly which case went wrong. In the first levels the list uses pictures, and 0 and 1 come later. LIGHT UP THE TOWN As you repair the circuits, dark devices switch on one by one and the town lights up region by region. STARS AND HINTS Every level has 3 stars: solve it, get it right on the first Test, and finish without hints. Stuck? Wire can help. Hints are paid for with coins you earn by finishing levels, or you can watch a short ad to get one. PHONE AND TABLET Plays in landscape. On tablets the circuit board and the list of tries sit side by side, and everything is bigger. Plays without an internet connection too. PRIVACY AND ADS • The game is free and needs reading. Menus and Wire's guidance come in 17 languages; the level stories are in English and Turkish. • No ads in the first 4 levels. From level 5, an interstitial ad may appear only after a level is finished, at most once every 3 levels and at least 3 minutes apart. Never in the middle of a level. • Ads are not personalized and are limited to content rated G (general audiences). The app never asks for tracking permission. • Optional purchases: 5 hints, 20 hints and Remove Ads. Every purchase and restore goes through a parental gate. • No account and no analytics. Progress is saved on the device only. Wire is waiting. Let's light up the town together!
