We present a description and an analysis of three related language games in Africa's Gulf of Guinea: Fa d'Ambô's Fa do Vesu, Lung'Ie's Faa di Vesu, and São Tomé and Príncipe Portuguese's P-language. We show how these language games can be used to investigate the linguistic features of their main languages and as learning resources for second language learners. First, we defend the common origin of these language games and that they emerged from contact with Portuguese settlers' Língua do Pê's varieties. Second, we discuss phonological issues, such as syllable structure, focusing on the loci of onglides, offglides, syllabic nasals, and word prosody. Finally, we discuss how these ludlings can help speakers, learners, and linguists perceive phonological properties as well as the contribution of describing and analyzing language games for language documentation.
