A drawing-driven 3D auto-battler where the weapon you sketch becomes a physical sword. Thin blades cut well and move quickly, heavy shapes smash through guards, and broad weapons catch incoming attacks. Build a connected blade, read its measured traits, and try to defeat eight increasingly strange opponents, from a schoolkid and sushi chef to Sasaki Kojiro and a giant Buddha.
Doodle Swordmaster, originally titled らくがき剣豪, turns a doodle into both your character build and your combat animation. You begin with a bare hilt on squared paper. Every line drawn from it adds pixels to a blade; press Fight and that exact silhouette becomes a three-dimensional weapon in the hands of a tiny swordsman.
The clever part is that shape is not cosmetic. A narrow weapon has a high sharpness percentage and swings quickly. A thick mass behaves like a club, trading speed for knockback and guard-breaking force. A wide outline creates more surface for catching an opponent's weapon. The result is a readable triangle of advantages rather than a hidden random score.

How to play Doodle Swordmaster
- Start drawing at the hilt near the bottom of the squared pad. Hold the mouse button or keep a finger down while tracing the blade. Separate grey pieces are not attached and will fall away, so make sure the weapon forms one connected shape.
- Watch the live measurements below the drawing: blade type, length, weight, sharpness, balance and handling all respond to the outline. Use Undo for the last stroke, Clear to erase everything, or Samples to study several working shapes.
- Press Fight! when the button becomes active. The game introduces the next rival and compares the two weapons before the duel. Combat is automatic, so the decision was your drawing; the small speed control can run the action at twice the normal rate.
- After a victory, keep the same weapon for the next opponent or return to the pad and redesign it. A complete run asks one blade to defeat eight different fighters, ending with the enormous Buddha.
- The Challenge menu can package a blade into a link or accept another player's code. Long self-contained links work locally; the shorter six-character codes rely on HedoroBomb's online challenge service and may be unavailable when offline.
Controls: Drag from the hilt across the drawing pad to make a blade. Undo removes the latest stroke, Clear starts over, and Samples cycles through example weapons. Press Fight when the blade is connected. Battles play automatically; the 2x button speeds them up. After a win, continue to the next opponent or redraw your sword.

Why it's worth your time
The drawing screen gives unusually concrete feedback. Length is shown in centimetres, mass in kilograms, and small labels explain why a shape behaves as it does. If it is too heavy to lift, disconnected from the hilt or comically short, the game says so before committing you to a fight.
Combat uses the outline as geometry rather than swapping in a generic sword model. Awkward hooks, giant paddles, needles and lopsided axes produce visibly different collisions. Fighters block, bind, lose balance and get launched according to contact, so even failed designs tend to create a funny, legible story.
The eight-opponent ladder keeps changing the problem. Early rivals teach basic cutting and guarding, while later weapons and body sizes punish a design that only excels in one matchup. Winning therefore feels less like finding a single maximum stat and more like building a shape that survives several kinds of collision.
HedoroBomb's own localisation is broader than the Japanese landing page suggests. English, Japanese, Traditional Chinese and Korean cover the menus, opponent dialogue, weapon descriptions and share cards. Language selection is available in the drawing screen and persists in local browser storage.
How it was made and where it lives
Hosted on the author's own page. The author publishes as HedoroBomb (戦力外ヘドロ爆弾). Original: https://hedorobomb.com/game/rakugaki-kengo/. The Play button runs an unofficial local mirror. It defaults to HedoroBomb's own English locale and adds an attribution notice; gameplay, art, audio, scoring and opponent data are otherwise unchanged. The original remains linked, and no endorsement or authorisation is claimed.
Frequently asked questions
- Is this an official English translation?
- The English text is official in the narrow sense that it is already built into HedoroBomb's game. Floating Arcade only makes that existing locale the default. This mirror itself is unofficial, non-commercial and is not presented as endorsed or authorised by HedoroBomb.
- What makes a strong sword?
- There is no universal shape. Thin blades are sharp and fast, heavy blades break guards and launch opponents, and broad blades are good at catching attacks. Keep the blade attached to the hilt and watch weight and handling before fighting.
- Can I play on a phone?
- Yes. Drawing, menus and battles use pointer events and large touch targets. The square pad resizes to fit the available screen, and no keyboard is required.
- Does it work offline?
- The core game, fonts and single-player ladder work from the local mirror without contacting the original site. Short challenge-code creation and lookup use an author-operated API, while sharing to X naturally needs a connection.
- Who made Doodle Swordmaster?
- HedoroBomb, also credited as 戦力外ヘドロ爆弾. The original game page, author profile and source game remain linked. Rights holders can request a correction or removal through the contact link in this site's footer.
- Is Doodle Swordmaster free to play?
- Free to play with no account or download. This is an unofficial, non-commercial mirror with the original author and game linked prominently.
- Can I embed this game on my own website?
- Yes — copy the snippet below. The embedded player links back here, which is how we ask to be credited.
