Zerovero is a free Android game developed by RSI Radiotelevisione Svizzera. It is a word game that is an extension of the television format of the same name. The objective of the game is to tie words together by way of links in a chain. There are two phases to the game. In Phase 1, you need to rebuild two chains starting from the two initial words given. Once you have found the correct sequence, you can proceed to Phase 2. In Phase 2, you need to find and write the word "Zerovero" that binds the two words resulting from the previous chains resolved in Phase 1.
