The break between indoor and outdoor forms caused many variants to diverge from the original Llargues version. Thus "Perxa" evolved into Galotxa, and which in turn gave rise to Escala i corda, while Raspall was still played in both courtfields. "llargues" is the only variant that uses the original ""ratlles"" rule, the others using a net to separate two sides on the playing area (as "galotxa", and "escala i corda"), or with no court division at all ("raspall"). Another case is the Frontó variety, which was first documented in the late 19th century, influenced by the popularity of the main Basque pelota variant, which involves players throwing the ball against a wall.
