# Games With Changing Rules: What Each Module Redraws - Author: Bomb Appétit (https://bombappetit.com) - Published: 2026-10-20 - Category: Rule seeds - Canonical: https://bombappetit.com/blog/games-with-changing-rules-what-each-module-redraws > Games with changing rules redraw some parts and keep others. A module-by-module table of what a new rule seed changes, and the one module it never touches. Games with changing rules rarely change everything. In Bomb Appétit, a new rule seed keeps the bomb, the controls and the shape of every manual page, and redraws the content inside: conditions, tables, word lists, mazes and codes. Thirteen of the 14 modules get new rules. One, Discharge Lever, is identical under every seed. ## Which games with changing rules keep the board fixed? The ones that stay learnable. If both the board and the rules moved, players would have nothing to hold on to. Bomb Appétit fixes the physical side: the same modules, the same controls, the same edgework. The rule seed only rewrites what the manual says about them, so skills carry over while answers do not. A Defuser who has cut wires under one seed knows how to cut wires under any seed. The wires look the same, the cutting works the same and the strike lights behave the same. What the Defuser cannot carry over is which wire to cut. That answer lives in the manual, and the manual is what the seed redraws. The same split applies to the Experts. Each module's page keeps its layout and its opening explanation. An Expert who has read the Big Button page before knows to look for a list of lines and a release section. The lines themselves are new. For the full list of what holds steady from seed to seed, see [what stays the same across seeds and what changes](/blog/games-with-random-rules-rule-seed-manual#what-stays-the-same-across-seeds-and-what-changes). Here is what a new rule seed redraws on each of the 14 modules. The table describes the kind of change. It does not quote any seed's actual rules. | Module | Kind | What a new rule seed redraws | | --------------- | ------- | -------------------------------------------------------------------------------------------------------------------------- | | Wires | Regular | The if-lines for each wire count (3 to 6): their conditions, their order and which wire each cuts, plus the otherwise line | | Big Button | Regular | Four or five tap-or-hold lines and their conditions, the fallback move, and the release digit for each strip color | | Glyph Keypad | Regular | Six columns of seven symbols: which symbols sit in each column and in what order | | Color Echo | Regular | The color tables: one per strike count, with separate sets for a serial with or without a vowel | | Word Grid | Regular | Which button to read for each display word, and the priority list for each button word | | Recall | Regular | The instruction for each display digit at each of the five stages | | Blinker | Regular | The pulse pattern for every letter and the frequency for every word | | Tangled Wires | Regular | The instruction for each combination of wire markings, and which port type the port rule asks about | | Wire Panels | Regular | For each wire color, which letters to cut at each occurrence | | Labyrinth | Regular | Nine mazes and the two marker cells that identify each one | | Passcode | Regular | The word list: 35 words chosen from a larger pool | | Pressure Vent | Needy | Which six questions appear and whether each answer is yes or no | | Discharge Lever | Needy | Nothing | | Dial Alignment | Needy | The light patterns and the dial direction each one asks for | The bomb's own contents are dealt by a different number, the bomb seed. That number chooses which modules appear, the edgework on the casing and the starting state of each module. If you want to know how a seed works in general, the guide on [what a seed is in games](/blog/what-is-a-seed-in-games-same-number-same-rules) starts from the beginning. ## Wires, Big Button and Passcode under a new seed These three modules change in three different ways. Wires gets new logic: different conditions and different targets in each list. Big Button gets new logic plus new release timing. Passcode keeps its logic and swaps its vocabulary, so the Expert searches a different list of words. **Wires** has one list per wire count, from three wires to six. Under any seed, each list has three or four if-lines followed by an otherwise line, and the Expert reads from the top until a line is true. A new seed changes what each line checks and which wire it points at. A line might ask about the serial number's last digit, the color of the last wire, or how many wires of a color are present. The target might be a numbered position, the last wire, or the first or last wire of a color. **Big Button** has four or five lines, each saying tap or hold, with a fallback move at the end. Each line checks one or two things: the button's color, its label, the battery count or a lit indicator. A new seed redraws the lines and the fallback. It also redraws the release table, which gives a digit for each color the strip can light up. The Defuser holds the button and lets go when that digit appears on the timer. **Passcode** has five wheels of letters on the bomb and a word list in the manual. The Expert looks for the one listed word the wheels can spell. A new seed chooses a fresh set of 35 words from a pool, so the list on the page changes while the method does not. The bomb only deals wheels where exactly one listed word fits. For a tour of what each of these modules asks the Defuser to do, regardless of seed, the guide to [Wires, Big Button and Glyph Keypad, the first three modules](/blog/bomb-defusal-puzzle-game-11-modules-explained#wires-big-button-and-glyph-keypad-the-first-three-modules) covers the faces and controls. ## Glyph Keypad, Labyrinth and Wire Panels: redrawn tables and mazes These three modules depend on a lookup the Expert scans by eye: columns of symbols, a set of mazes, or a cut table. A new seed rebuilds that lookup from scratch. The way to use it stays the same, but anything an Expert remembered about where things sit is gone. **Glyph Keypad** shows four symbols on the bomb. The manual has six columns of seven symbols, and exactly one column holds all four. The Expert presses them in the order that column lists them. A new seed draws new columns. The generator also requires each column to share several symbols with the others, so spotting one familiar symbol never identifies the column on its own. **Labyrinth** shows the Defuser a grid with two markers, a position and a goal, but no walls. The manual holds nine mazes, each identified by where its two markers sit. A new seed carves nine new mazes and places new markers. Under one seed, a marker in a given corner might belong to one maze. Under another, that corner may belong to a different maze or to none. **Wire Panels** shows four panels, one at a time, each with up to three wires. A wire runs from a numbered post on the left to a lettered post on the right, and it is red, blue or black. The manual has a table per color that says, for the first, second and each later appearance of that color, which letters mean cut. A new seed rewrites all three tables. Keeping count out loud matters on every seed, because the table depends on how many wires of that color have appeared so far. Glyph Keypad, Labyrinth and Wire Panels are where memory of an old seed does the most damage. An Expert who half-remembers a column or a maze tends to read it with confidence, and a confident wrong answer is still a strike. ## Do needy modules get new rules with each seed? Two of the three do. Pressure Vent and Dial Alignment both read their answers from the manual, and a new seed redraws those answers. Discharge Lever has no manual answers to redraw, so it plays the same under every seed. How often each needy module wakes is not part of the rules at all. **Pressure Vent** wakes up and asks a yes or no question. The manual lists six questions and the answer to each. A new seed chooses which six questions appear, from a larger pool, and whether each one is answered yes or no. The generator insists on at least two yes answers and two no answers, so the Defuser can never guess safely. **Dial Alignment** wakes up with a pattern of lights. The manual matches each pattern to a direction for the dial. A new seed draws new patterns, each with four to eight of twelve lights lit, and assigns them to directions so that each direction appears twice. The generator rejects any set where two patterns look the same. The timing of needy modules is set by the bomb, not by the manual. When a needy module first wakes, how long it stays awake and how long it sleeps afterwards come from the bomb's own randomness. A new rule seed changes what the Expert reads, not when the Expert is needed. For the full picture of how they behave during a round, the guide on [what needy modules do while the others are being solved](/blog/needy-modules-never-stay-solved#what-needy-modules-do-while-the-others-are-being-solved) explains the wake and sleep cycle. ## Discharge Lever: the module the seed leaves alone Discharge Lever is the only module whose rules are empty. Its generator returns nothing, so every seed gives it the same manual page. A meter fills on its own, a full meter is a strike, and the Defuser holds the lever to drain it. No Expert input is needed under any seed. The manual page says exactly that. It tells the Expert that this module needs no expert help, and it describes what the Defuser should do: hold the lever down while the meter drains and let go once it is empty. There is no table to look up and no condition to check. That makes Discharge Lever a useful landmark for a team switching seeds. It behaves identically on a seed 1 bomb and on any other bomb. If a team is unsure whether a strike came from reading the wrong manual, a strike on Discharge Lever cannot be the reason, because there is nothing on its page to get wrong. It also shows that a seed changes rules, not mechanics. Discharge Lever still has its own timing: when it starts and how fast the meter fills come from the bomb, not the manual. The seed simply has nothing to say about it. A module only changes with the seed if its manual page has something to decide. The module still appears only when the bomb is dealt with needy modules. In freeplay, the needy count can be set from zero to three, and needy modules are drawn from all three. Some missions use it too. ## The changing rules mistake: trusting a module page from last week The mistake is reading a page you remember instead of the page in front of you. A group plays seed 1 for weeks, then tries another seed, and one Expert answers from memory because the page looks familiar. The layout is the same, so nothing looks wrong. The answer is from the wrong seed. It shows up most on the modules with lookups. A Glyph Keypad column, a Labyrinth maze or a Wire Panels table is easy to half-remember and hard to double-check under time pressure. A Wires list feels familiar because the conditions are short and the colors are the same words. A few habits prevent it: - **Read the seed before the page.** Every manual shows its seed at the top of its first page. Say it out loud at the start of the round. - **Look it up every time.** Even on seed 1, read the line rather than reciting it. It costs a second and catches a seed change. - **Keep printed copies labelled.** A printed seed 1 stack sitting beside a laptop on another seed is an easy trap. The number is on the paper; check it. - **Ask a second Expert on lookup pages.** When two Experts reach the same answer from the page in front of them, a stale memory is unlikely to be the source. The rule seed is printed at the top of every manual's first page. The short guide to [the rule seed number on every manual](/blog/what-is-a-rule-seed-number-on-every-manual) lists the other places to find it. To try a page under a new seed, open [manual 1](/manual/1) and change the number in the sidebar.
