UNDERTALE: The Determination Symphony World Tour plays Esplanade Theatre on Monday 21 and Tuesday 22 September 2026 at 8pm. Tickets start at S$78, with Cat 1 seats listed at S$158, via Esplanade and SISTIC.
What the concert is
A 25-piece Metropolitan Festival Orchestra, conducted by Thanapol Setabrahmana, performs newly arranged themes from Toby Fox’s indie game while gameplay footage runs above the stage. The programme moves through the Underground arc from the Ruins and Snowdin to Waterfall, Hotland and New Home. Runtime is about two hours including a 20-minute interval. Admission is age 6 and above.
Tickets and seating notes
Esplanade lists Cat 1 through Cat 6, including restricted-view Cat 6 and Box B to G seats sold at Cat 3 prices. Rows A to C in the Stalls that were first tagged as Cat 1 are offered at Cat 3 because of restricted viewing, with no exchanges or refunds after purchase. Booking runs through Esplanade’s site and SISTIC event code undertale0926.
Why a second night
The Tuesday 22 September date was added after strong demand for the first Singapore show. Anyone still hunting seats should check both nights before the mid-September window tightens further.
