RTP Chili Chomp Ultra Up is a 5-reel, 40-line slot from Lightning Box with an RTP range of 94.14% to 96.03% and a top prize of 5,564x. The game was released in February 2025 and includes a minimum bet of 0.4 and a maximum bet of 40.
Its main mechanics centre on Ultra Up Respins, where Scatter Skull symbols can trigger a Hold & Spin feature with three spins. Chili characters upgrade as more land on the same frame, while additional characters unlock extra rows on the grid, increasing the chance of higher multipliers and more symbol combinations.
Bonus symbols trigger Free Games with two options: 12 spins with constant Wilds, or 6 spins with Extra Wilds. The demo version is available to play for free, allowing players to explore the features and practice before playing for real money.
