"Big Casino" is a song by American rock band Jimmy Eat World from their sixth studio album Chase This Light, which was released on October 16, 2007.

Slant Magazine's Jonathan Keefe said it wasn't as powerful as "The Middle", but gave it praise for having "a memorable guitar riff and [exploding] into a massive chorus.

"[5] Brian Hiatt of Rolling Stone was critical of the song's use of synths but still praised it as "an exhilarating seize-what’s-left-of-the-day anthem.

"[6] Despite giving a negative review of the album and criticizing the track's lyrical missteps, Andrew Blackie from PopMatters called it "a decent rocker with one of the best examples of a soaring ‘emo’ chorus of the year.

It is at a slower tempo and incorporates piano, acoustic and electric guitars, drums and strings, along with Fishel's layered vocals and multiple harmonies.
