As it turns out, the story is more complicated than that.
At NY Toy Fair 2020, which I attended after recording the video posted below, I happened to run into Andy Daniel, who was running an Enginuity booth and selling Spicy Dice — except that he wasn't selling the Spicy Dice game collection from 2004, but a standalone game called Spicy Dice that was not included in that earlier collection, a standalone game that Daniel released through Enginuity in 2018, a standalone game that Daniel had licensed to AMIGO, which had changed the name to Chili Dice.
Daniel mentioned during our conversation at NY Toy Fair that he was much more of a designer than a marketer, which is a fair thing to say given that Spicy Dice — the new one — didn't have a BGG listing until I made one to accompany this posting.
In any case, here's an overview of Chili Dice, which is available in the U.S. under one name and in Germany under another. Either way, the game plays the same. In general, Chili Dice is akin to Yahtzee as each player will roll dice and score separately in multiple categories such as points for 1s, straight, and chance.
Where Chili Dice differs from that earlier game is that players have at most thirty rolls during the entire game, with them being able to allocate as many rolls as they want across the ten categories in which they'll score. Roll five 4s and want to press your luck rolling a sixth 4 to grab 75 points? Go right ahead!
The red faces on the dice are the other element that differs from Yahtzee. When you roll a red face, you can change that die to any number you want, which is great for creating a straight of six numbers or creating pairs and triples. If you keep a red face, however, you can gain bonuses in different ways. If you're collecting dice showing a single number from 1 to 6 and you have the red face showing that number, then the sum of those dice is doubled. Four 6s is 24 points, but if one of those dice is red, then you have 48 points. If you have a straight with a red 1, then you can score those 21 points in a straight like normal, or you can score 21 points in the 1 category, which normally doesn't net you many points.
If you fill all the categories, then you score 5 points for each roll unused — but winning scores in my six non-solo games on a review copy from AMIGO have typically been 300 points or more, which means that players are averaging at least 10 points per roll, which means you'd probably be better off rolling repeatedly to maximize your score in various ways instead of stopping early.
I go into more detail about the gameplay, the scoring categories, and why puzzle-based games aren't the same as puzzles in this video:
