About Skulls Up

Cee-lo—derived from sì wǔ liù (Chinese for “four-five-six”)—is played with three six-sided dice. Popular among Chinese-American players as early as 1893, it was adopted by hip-hop culture in the late 1970s and became a fixture on the street corners of Harlem, Brooklyn, and the Bronx.

Nas, the Notorious B.I.G., and Jadakiss all referenced the game in their music. Kool G Rap called his 1995 album 4,5,6, and its title track included the line “Headcrack, time to get the bread”—the lyric that most likely inspired 50 Cent’s casino adaptation.

But it was Thomas DeCarlo Callaway who gave the game its biggest mainstream exposure, and gesture of love, when he took his stage name, CeeLo Green, directly from it.

According to TCS/JOHNHUXLEY, 50 Cent Headcrack is designed to attract players who are not already at the tables, and to keep the game moving once they sit down, while preserving Cee-lo’s essential drama: three dice, one shooter, and the hope of rolling a 4-5-6.

How to play Skulls Up

The Digital Asset Market Clarity Act, a long-hyped piece of legislation establishing a federal framework for cryptocurrency, failed to clear a key Senate vote this week and now looks dead for 2026. It represents a resounding defeat for crypto stakeholders with multiple ramifications for the gaming industry.

At least 60 “yes” votes were needed to move the legislation towards passage, but the final tally of 49-50 didn’t even reach a majority after four Republican lawmakers broke ranks to oppose the market structure bill. With critical midterm elections approaching in November, there is little chance that the issue will be picked back up in the balance of the Congressional session.

Notably, ethics concerns may have played a critical factor in the rejection of the bill. Lawmakers from both sides did not feel that an updated version of the text released on Sunday went far enough in addressing concerns related to senior officials maintaining or endorsing crypto business ties. However, a group of Republicans claimed they made a series of concessions when US President Donald Trump agreed to modifications on Sunday night that contained stronger ethics measures, the Associated Press reported. The 11th hour concessions were not enough to appease potential swing voters among Senate Democrats.
