Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
Think about sudoku, but reinvented!
This game has just a few simple rules:
You have to fill a 4x5 grid with numbers from 1 to 5, ensuring that each row and column won't have duplicates and that the sum of each row’s numbers gives the result on their right side.
Also, you must insert all five numbers (1,2,3,4,5) into the two colored sections on the grid.
Each puzzle has a unique solution. It's relaxing, but still pretty challenging.
If you want to spice up the challenge, play • zenku • in YinYang mode and complete the puzzles within 2 minutes!
Will you complete all 100 zenku puzzles?

I've only done a handful of these, but it's more frustrating than relaxing to find something that follows all the rules, but doesn't advance the game. It seems like the game is programmed to only recognize one specific answer, and not any others that may still solve the puzzle.
