Río divides into rí-o: its last syllable is o. In an editorial Spanish chain, río → oso → sopa → pato therefore joins through o, then so, then pa. This explains Alicia’s rule; it does not guarantee those words appear together in a game.
A single vowel can be the next link
In rí-o → o-so, the final o of río and initial o of oso form the link. Next, o-so → so-pa uses so and so-pa → pa-to uses pa. If someone suggests ropa after río, its opening ro does not match o. These are editorial Spanish examples, not an observed hand. Keep the Spanish words and accent; translating changes the joins.
The RAE spelling reference includes río among hiatus examples with a stressed close vowel. Here, keep rí-o when checking the link; a game need not become a terminology test.
Bring the check to Alicia
The Alicia facts describe a local Spanish game. In family mode, Peque chooses among three picture-and-syllable cards and Adulto among six text cards; together they build a cooperative ten-link chain. After an adult success, Peque checks the connection. Look at the word and options actually shown rather than requiring an example card.
In Rally, Peque proposes a word and Alicia continues. The documentation consulted does not specify how accents are validated or which words are available, so we do not assume either. Words remain visible and audio is optional.
