Guinea-Bissau’s gambling culture is small, informal, and shaped more by a state lottery and offshore football betting than by any casino scene. Its defining modern moment was an August 2019 government order that restricted games of chance after a wave of unregulated slot machines. Attitudes are tempered by a religiously mixed society in which Islam, the largest single faith, generally discourages gambling. Published data on this market is limited, so this overview stays qualitative where the facts are thin.

A Portuguese-era institutional backdrop

Guinea-Bissau was Portuguese Guinea until independence in the 1970s, and Portuguese remains the official language, with Kriol widely spoken as an everyday lingua franca. Like several Lusophone countries, it operates a national lottery — Loteria Nacional da Guiné-Bissau (LONAGB) — which functions as the state’s main sanctioned gambling channel. State lotteries in this tradition are typically framed as raising funds for social causes rather than as commercial gaming.

The 2019 order and the “Colos Colos” machines

The most significant recent chapter is the 2019 crackdown. From around 2017, unregulated slot machines — locally nicknamed “Colos Colos” — spread quickly, largely outside legal oversight. In August 2019 the State Secretary of Tourism and Crafts, Catarina Taborda, signed an order restricting games of fortune and chance, on the grounds that the activity was happening in a disorganised way outside legal norms and that minors were participating. According to local reporting, the measure was a suspension, with any resumption tied to standards the tourism authority would later set. The state lottery remained the recognised sanctioned channel.

Football betting and a young, connected audience

As elsewhere in West Africa, football is the emotional centre of betting culture. With no local licensed online operators, interested bettors turn to offshore sites, mostly for football and other sports. This activity is informal and unsupervised by any Bissau-Guinean authority, so figures on its size are not reliably published.

Religion and social attitudes

Guinea-Bissau is religiously plural, with no single majority faith. Widely cited estimates put the population at roughly 46% Muslim, about 31% following traditional African religions, and around 19% Christian, with a high degree of syncretism and peaceful coexistence. Muslims are concentrated in the north and northeast, Christians along the coast and south. Because Islam generally discourages gambling, attitudes are often cautious or disapproving, particularly in Muslim-majority areas, even where informal betting still occurs.

A market defined by absence

More than anything, Guinea-Bissau’s gambling landscape is defined by what is missing: no dedicated regulator, no online licensing regime, no formal player-protection framework, and little reliable published data. The state lottery and the 2019 order are the clearest documented reference points; almost everything else is informal, offshore, or unquantified.
