Winna Plinko Verification Tool

Compare your Plinko outcomes against fair binomial math. Enter your seed pair and nonce range to see if any results were affected by the December 17 – March 2026 probability modification.

Affected period: December 17, 2025 – ~March 10, 2026. During this period, Winna's Plinko used hardcoded probability tables instead of standard binomial distribution. This tool compares what the modified code produced against what fair Plinko math should have produced. You need your unhashed server seed (available after seed rotation) and client seed from your Winna bet history.

Methodology

This tool implements two Plinko algorithms and compares their outputs for each nonce:

Winna's algorithm (Dec 17 – Mar 2026): Generates a single float via HMAC-SHA256(serverSeed, clientSeed:nonce:cursor) and maps it against hardcoded probability tables. These tables were extracted from Winna's production JavaScript, independently archived by the Wayback Machine on January 27, 2026 (-kePZzxf.chunk.js).

Fair binomial algorithm: Generates one float per pin row using the same HMAC byte generator, counts how many are ≥ 0.5 (equivalent to per-pin left/right coin flips). This produces the standard binomial distribution that all fair Plinko implementations use.

When the two algorithms produce different buckets for the same seed/nonce, the bet was affected. The impact shows the multiplier difference per $1 wagered.
