A blocky world where every night is a Demon Slayer hunt. Mine ore, forge a Nichirin blade, master a Breathing Style, and cut through the dark.
Demoncraft v1.16 — Demon Slayer Edition
Every game in the Dea Durro world, in one place. Pick a challenge — your best scores are saved as you play and shown on each card.
Open the book. Read the first page of the slayer's log.
I spawned at the edge of a cursed forest. The sun set fast, and the first demon rose from the blocks before I'd even crafted a sword. I survived. Barely.
They call me Dea Durro — a wandering slayer who builds by day and hunts by night. My world runs on two rules: breathe, and endure. Every cobblestone I place, every blade I forge, sharpens the next strike.
This place is part Minecraft, part Demon Slayer Corps. Mine the breathing styles below. Forge a slayer of your own. Then climb the night, advancement by advancement.
1/1Each style is an enchanted Nichirin blade. Hover a slot — every blade has its own power and forms.
Flowing, adaptable forms that bend like a river around any demon. Calm power, ten unbroken strikes.
Roaring offensive style of the Flame Hashira. Set your soul ablaze and burn through the night.
One blinding step. Thunderclap and Flash — close the distance before the demon even renders.
Wild slashing gusts that cut from every angle. Relentless pressure, never a still moment.
Feed ore to the grid, pull the result, then dye your slayer. Combine colors and craft a one-of-a-kind hunter.

Tap cells to place ore — 🟥 🟦 🟨 🟩 🟪 ⬛ — plus a ☀️ Sunstone to awaken it, then click the blade to forge. The dominant ore sets your Nichirin colour.
Your forged slayer enters an endless gauntlet. Each round, a stronger demon. Win to advance — your wounds carry over, but every victory heals you. How deep into the night can you survive?
Swap two neighbouring blocks to line up 3 or more of the same breath. Clear each round's goal before your moves run out — then push into the next, harder round. How deep into the night can you climb?
Tap a block, then tap a neighbour to swap · longer lines & cascades score more
Walk your slayer through each cursed room and push every demon coffin (🟪) onto a glowing seal (🟩). Seal them all to clear the level and walk deeper into the night.

Your slayer sprints through the endless night. Jump the demons and pits — or slash a demon for bonus points. The longer you run, the faster it gets. How far can you cut through the dark?

Flip the cards two at a time and find the matching pairs of demon-slayer symbols. Clear them all to advance — each round adds more cards. Fewer flips earns more stars.
Tap two cards to flip them · matches stay face-up · a perfect round is one flip-pair per match
Channel the Serpent Hashira: weave across the grid and devour demon souls (🔮) to grow longer. The longer you get, the faster you slither — don't strike a wall or your own coils.
←↑↓→ / WASD steer · or swipe the board
Slide the soul-orbs and merge matching numbers to forge ever-greater spirits. Reach 2048 to seal a Demon King — but the board fills fast, so plan your slides.

Bounce your Nichirin blade-orb off the paddle to shatter the demon bricks. Clear the wall to advance — each level packs in more demons and a faster orb. Don't let the orb fall past you.

Master the forms by memory. Watch the breathing styles light up in sequence, then repeat them in the exact order. Each round adds one more form — how long a kata can you hold in your mind?
Watch 🌊🔥⚡🌪️ flash, then repeat the order · the sequence grows by one each round
Carry the Corps' message through the night. Flap the Kasugai crow to keep it aloft and thread the gaps between the torii gates. One clipped wing ends the flight.
Space / click / tap to flap
Demon blades scream in from every edge. Slip between them and survive as long as you can — the longer you last, the thicker the storm. Grab 🔮 souls for bonus time.
Mouse / drag / ←↑↓→ / WASD to weave through the blades
Forge falling blocks into solid walls. Slot the tetrominoes together and complete full rows to clear them. Stack to the top and the forge is lost — it only gets faster.

Raise a pagoda toward the blood moon. A block slides side to side — drop it onto the tower as squarely as you can. Any overhang is sliced away, so each block only gets narrower. How high can you build?
Space / click / tap to drop the block
A duel of wits with a demon. You are the blade 🗡️; the demon is 👹. Place three marks in a row — across, down, or diagonally — before it does. On Hard, the demon never makes a mistake.

Sink your fangs into the demon's defense. Drop blade-discs down the columns and line up four — across, down, or diagonally — before the demon connects its own.
Tap a column to drop your disc · connect four to win · the demon drops back
Break the demon's secret 4-colour code in 10 guesses. After each guess you get pegs: a gold peg = right colour in the right spot, a pale peg = right colour, wrong spot. Deduce the order.
Tap colours to fill the row, then Guess · gold = exact, pale = right colour wrong spot
Read the flow of fate. A card is drawn — wager whether the next will be higher or lower. Guess right to build your streak; one wrong call and fate turns. Ties are spared.

A gambler's duel with a demon — first to 50. Keep rolling to pile points into your turn, then bank them. But roll a 1 and the demon snatches your whole pile and takes its turn. Greed is a blade with two edges.
🎲 Roll to build · ✋ Bank to keep · rolling a 1 loses the pile · first to 50
See past the deception. A breathing word appears in coloured ink — decide fast whether the word matches the ink colour it's written in. Your mind wants to read; train it to truly see. 30 seconds.

Embers rain from a burning sky. Sweep your basket to catch the 🔥 embers for points and snag a rare 🌟 Hashira spark for a bonus and an extra life — but never catch a 🌸 wisteria petal, or the demon within it steals your heart. Lose all three and the night wins.
Mouse / drag / ←→ / A D to sweep the basket · catch 🔥 · avoid 🌸
A five-letter word hides in the wisteria. Guess it in six tries — a green tile is the right letter in the right place, an amber tile means the letter is in the word but misplaced, and a grey tile means it isn't there at all. Solve it to grow your streak.

Rivers of demon blades sweep across the path. Hop up lane by lane and reach the ⛩ torii gate at the top to score, then do it again as the blades quicken. One touch costs a life — lose all three and the night takes you.
←↑↓→ / WASD or tap a direction to hop · reach the ⛩ gate
Demons pour down from the black sky. Slide along the ground and loose Nichirin shots to cut them from the air — the longer you hold, the faster they fall. Let one reach the ground and it costs a life; lose all three and you're overrun.
Mouse / drag / ←→ / A D to move · Space / ↑ / tap to fire
Old wards hold the demons at bay — but the sealing stones have been knocked loose. Push each stone onto a glowing ◆ seal to close the ward. Stones only slide, so shove one into a wall or corner and you'll have to reset. Close as many seals as you can.
←↑↓→ / WASD or tap to push · R reset seal · U undo
Total concentration reveals what others miss. One tile in the grid is a hair's shade different from the rest — find and tap it before the timer runs out. Each find sharpens the challenge: bigger grids, subtler differences.
Tap the odd tile before the bar empties · it gets subtler each level
A clear mind counts fast. Solve each reckoning and strike the right answer before the bar empties. The sums grow sharper as your streak climbs — how many can you cut through in the time given?
Tap the correct answer before the round bar empties · sums get harder as you go
Corruption has stained the ground in many colours. Starting from the top-left, choose a colour to flood your growing region — spread it until the whole board is cleansed to a single colour. But you only have so many purges before the demon takes root.
Tap a colour to flood from the top-left · fill the whole board in one colour to win
Under the eclipse, the board turns. Place a disc so it flanks a line of the demon's discs between yours, and they all flip to your side. When neither can move, whoever holds the most discs wins the night.
Tap a dotted square to place a disc and flip the demon's line · most discs wins
