Master DSA visually in real‑time 3D, with spatial audio.
Stop memorizing algorithms. Watch 3D isometric pillars lerp dynamically, hear musical comparison frequencies, trace synchronized Python, and internalize FAANG interview logic.
This runs live — right here.
Floating 3D pointer badges, realistic soft shadows, and step-by-step intuition — for Bubble Sort, Binary Search, Quick Sort, Two Pointers and 100+ more.

3D spatial pillars
Glossy platform with contact shadows and dynamic height scaling. Blocks lerp and swap in real 3D coordinates.
Musical audio chimes
Zero-dependency Web Audio synth. Pitch tracks element value, with swap pops and a victory arpeggio.
Synchronized Python
Syntax-highlighted editor highlighting the exact executing statement in real time — visual state to real code.
Step intuition & tips
Plain-English reasoning for every step, plus curated FAANG interview tips for each algorithm.
Supported algorithms
From beginner essentials to interview-favourite divide & conquer paradigms.
Bubble Sort
Repeatedly swaps adjacent out-of-order elements to bubble values to the end.
Binary Search
Logarithmic search-space reduction by halving boundaries on sorted input.
Two Pointers
Converging left and right pointers reduce O(n²) pair search to linear time.
Quick Sort
Divide & conquer partition with a live pivot pointer and recursive sorting.
Insertion Sort
Adaptive, online sorting by inserting each element into its sorted sub-array.
Selection Sort
Minimizes writes by finding the absolute minimum and swapping it into place.
