The ultimate Dungeon Master companion. Track initiative, HP, conditions, spell slots, dice rolls, and session notes — all in resizable, draggable panels.
Run → Captain SonarCrew coordination companion. Coordinate Captain, Second Mate, and Engineer actions each turn.
Play → Tic Tac ToeClassic two-player game. Take turns placing X and O — first to three in a row wins.
Play → Ultimate Tic Tac ToeNine boards in one. Win mini-boards to control the meta-grid — your move dictates where your opponent must play.
Play → Dots and BoxesDraw lines between dots to complete boxes. Claim a box and take another turn — most boxes wins.
Play → PathfindingPaint walls, set a start and goal, then watch A*, BFS, DFS, Greedy, or Dijkstra's find a route. Edit the algorithm code live.
Explore → Pathfinding — Unknown MapAI navigates using its known map, discovering obstacles only within its vision radius. Draw new walls mid-run and watch it replan or explore to find a route.
Explore → GOAP PlannerDefine a world state, a goal, and a set of actions with preconditions and effects — then let A* find the optimal plan.
Plan → Behavior TreeBuild and step through a behavior tree. Add control, decorator, and leaf nodes — then evaluate to see exactly how the tree flows.
Build → Minimax VisualizerStep through minimax on tic-tac-toe. Edit the heuristic live, watch values propagate up the tree, and see which move the algorithm selects.
Explore → Bayesian Enemy TrackerFire observations (spotted, sound, footstep, gunshot, area clear) onto a building map and watch a probability distribution update Bayesian-style — prior × likelihood, renormalized.
Explore → Unit CircleInteractive unit circle with reference triangle, tangent and cotangent lines. Enter an angle or click to explore exact trig values at all special angles.
Explore → AI Probability TrackerControl a player on a grid while an AI hunts you using a live probability distribution. Watch certainty diffuse, collapse, and rebuild as the AI searches.
Play → Interpolation VisualizerExplore easing functions and animation curves. Choose from 30+ interpolation methods, watch the curve, and see an object animate using the selected easing function.
Explore → Dot Product VisualizerVisualize how the dot product works in 2D. Adjust vectors and see both the component form and magnitude-angle form equations updated in real-time.
Explore → Cross Product VisualizerExplore the cross product in 3D (visualized in 2D). See how the magnitude relates to the parallelogram area, and understand the direction with the right-hand rule.
Explore → BuzzerGame show buzzer with millisecond precision timing. Choose your sound, buzz in, and lock out for 20 seconds — great for trivia nights.
Buzz → HitsterThe music timeline game powered by Spotify. Place songs in the correct chronological order, earn guess points for naming the song and artist, and redeem them for a second chance.
Play → Chore ChampionsA colorful chore tracker for two kids. Earn points, complete chore groups to unlock prizes, and celebrate with confetti and sounds!
