Jumanji: Welcome to the Jungle, made one specific and clear reference to the original film, but that wasn’t the only reference to the 1995 Robin Williams feature that was included in the follow-up.
You probably caught the reference to Alan Parish, the character that Robin Williams played in the first Jumanji and the fact that one Jumanji board game piece ends up being discovered by our main characters was also made obvious.
The large statues that are visible near the end of the film, also reference the board game pieces from the first film.
However, there was another board game related easter egg that wasn’t specifically pointed out and thus might have been missed.
