The collection

Chroma Flood thumbnail

Chroma Flood

Flood-fill colored regions from a corner to conquer the board. Locked regions add layers of strategy — plan your colors wisely.

Orbit Keeper thumbnail

Orbit Keeper

Keep planets in stable orbits by adjusting their velocity vectors as rogue asteroids and solar flares create chaos.

Strategy / Physics

Symbiosis thumbnail

Symbiosis

Control two linked organisms — a tough Host and a nimble Parasite. Use the elastic tether between them to clothesline waves of enemies.

Action / Strategy

Medium
Drift thumbnail

Drift

A zero-friction momentum puzzle. Push off walls and drift through hazardous rooms. No legs, no brakes — just pure ghost momentum.

Puzzle / Arcade

Medium
Spectrum thumbnail

Spectrum

Place estimates on a number line and bet your confidence from 1x to 5x. Build nerve chains with bold accurate guesses — but miss big and the chain breaks.

Puzzle / Strategy

Medium
Déjà Vu thumbnail

Déjà Vu

Shapes appear one at a time — answer "New" or "Seen before." Decoy shapes that differ by just one property add psychological challenge. Rewards speed, accuracy, and streaks.

Puzzle / Arcade

Slide Devil thumbnail

Slide Devil

A troll platformer with zero friction. Floors vanish, gravity flips, exits teleport, and controls reverse — all while you slide uncontrollably.

What's Missing? thumbnail

What's Missing?

Memorize a procedurally generated scene, then spot what disappeared. Five themed worlds — rooms, kitchens, parks, space, and ocean — with hybrid controls that shift from multiple choice to click-the-spot as difficulty ramps up.

Puzzle / Arcade

Cascade thumbnail

Cascade

Numbers rain into columns. When adjacent numbers sum to 10, they explode — triggering chain reactions that multiply your score. One smart placement can set off a 15-combo cascade.

Puzzle / Arcade

Ricochet thumbnail

Ricochet

One shot per level. Your bullet bounces off walls and must hit every target in a single ricochet chain. Aim, fire, watch. 30 levels of increasing precision.

Puzzle / Action

Burn thumbnail

Burn

Place ignition points on a procedural map. Fire spreads through grass, trees, and buildings — but stops at water and stone. Burn exactly the target percentage. Too much or too little and you fail.

Strategy / Puzzle

Medium
Rift thumbnail

Rift

Your movement leaves a dimensional rift. Enemy bullets that touch your trail warp through it and redirect toward enemies. No weapons — your trail IS the weapon. Weave, redirect, survive.

Action / Arcade

Hard
Morph thumbnail

Morph

A shape-shifting auto-runner. Switch between 4 forms — Runner, Ball, Glider, and Spike — each with unique physics. Chain morphs for combos, smash through walls as the Ball, soar over pits as the Glider, and ground-pound as the Spike.

Action / Arcade

Dendrite thumbnailNew

Dendrite

Build neural pathways by connecting related concept nodes. Fire signals through your network — correct paths glow, wrong ones decay. A neuroscience-inspired word-association puzzle.

Puzzle / Strategy

Medium
Phylo thumbnailNew

Phylo

Creatures appear with visible traits — body type, covering, limbs, eyes, and patterns. Place them on a branching evolutionary tree based on shared characteristics. Wrong placements crack branches.

Puzzle / Strategy

Medium
Convect thumbnailNew

Convect

Place heat sources and cold sinks to create convection currents. Particles ride the flow to goal zones — you never touch the particles directly. A thermodynamics puzzle with real fluid physics.

Puzzle / Physics

Medium
Phase Shift thumbnailNew

Phase Shift

An auto-scrolling runner across two overlapping dimensions. Toggle between Phase A (cyan) and Phase B (magenta) — obstacles in your active phase are solid, the other phase is ghosted. Four movement modes (Dash, Glide, Flip, Wave) activated by portals mid-level. 10 hand-crafted levels of escalating difficulty.

Hard
Contagion thumbnailNew

Contagion

The board is infected. Place cure nodes that emit healing waves — but the infection evolves resistance to your most-used strategies. Stay unpredictable or be overwhelmed.

Strategy / Puzzle

Hard
Splinter thumbnailNew

Splinter

Launch an orb that fractures on impact. Each split halves your mass — lighter pieces fly faster but can't break barriers. Merge splinters to regain power. Control one at a time, let others drift. Hit every target across 30 levels.

Puzzle / Physics

Medium
Chorus thumbnailNew

Chorus

Record short runs, then all recordings play back simultaneously as ghosts. Coordinate your past selves to hold switches, push blocks, and break walls so your final self reaches the exit.

Afterplay thumbnailNew

Afterplay

Anthology roguelike. Twenty famous arcade fragments — Tetris, Suika, Pac-Man, Wordle, Snake — drafted together with Tokens that rewrite the rules between rooms.
