Stop Grinding.
Start Building.
Break algorithm problems into reusable code bricks, then lock them into memory with spaced repetition. Learn the patterns once. Solve problems forever.
There’s a Better Way
The Old Way
- ×Grind 500 coding interview problems
- ×Forget solutions after a week
- ×No transferable understanding
- ×Cramming before interviews
The CodeBricks Way
- Learn 88 reusable patterns
- Spaced repetition locks them in
- Each pattern applies to 5-15 problems
- Confident, not cramming
Science-Backed Retention
Without review, you forget 80% within a week. Spaced repetition changes that.
~20%
retained after 1 month without review
~90%
retained with spaced repetition
5x
fewer reviews needed vs cramming
How It Works
Three steps from zero to interview-ready.
Learn the Bricks
Each brick is a fundamental coding pattern: two pointers, sliding window, DFS traversal. Study it, type it, master it through progressive repetition.
Review with SRS
Our spaced repetition system brings bricks back at the perfect moment. Four review modes keep it fresh: type it, fill blanks, reorder, multiple choice.
Solve Real Problems
When your bricks are strong, compose them into full interview-style solutions. 486 problems from top interview lists, each broken into their component bricks.
