## What is TriCunx?

TriCunx is an interactive probability simulator that brings statistical concepts to life. Drop balls through dynamic boards and explore Binomial, random walk and Geometric distributions in real time. Watch randomness transform into patterns, visualise outcomes, and experiment with probability models through engaging, interactive ball cascades. Perfect for students, educators, and curious minds, TriCunx makes abstract statistics tangible and visually compelling.


## Version history (last 5 releases)

### 1.3.8 — 2026-04-29

New analytical overlay based on an exponentially tilted arcsine distribution in ArcSine Drift Board, improving accuracy and providing smooth, controllable bias in the drift curve.

### 1.2.2 — 2026-03-31

Displays a single trajectory line within the triangle to provide an intuitive visualisation of how the balls interact with the pegs and are sorted into bins.

### 1.2.1 — 2026-03-29

Added Pascal, Poisson, and Negative Binomial distributions. Displays a single trajectory line within the triangle to provide an intuitive visualisation of how the balls interact with the pegs and are sorted into bins.

### 1.1.1 — 2026-03-26

Added ArcSine and Geometric distributions, and a new scaled binomial simulation feature.

### 1.0.1 — 2026-03-12

Explicitly label the right Y-axis as the count of falling balls and draw the histogram dynamically.
