DELTARUNE Fight Simulator Description
DELTARUNE Fight Simulator is a free browser game that collects more than 300 DELTARUNE and UNDERTALE fights in one tab. The battles are rebuilt line by line from the original games' battle code, so the attacks, the ACTs, the spells and the text work the way you remember. Pick a fight from the searchable list, command Kris, Susie and Ralsei on your turn, then steer the red SOUL through the bullets until the enemy is beaten or spared. The fight list sorts by chapter and covers every boss and regular enemy from DELTARUNE, plus UNDERTALE encounters like JEVIL, Spamton NEO and Sans. Boss rush chains a whole chapter's bosses back to back, a gauntlet and a daily challenge cover shorter runs, and twists such as Gravity, Pacifist and No Mercy rewrite the rules of a fight. If one pattern keeps ending your run, the toolbox has practice, rewind and slow motion, so you can drill a single attack until it sticks. If you would rather watch than dodge, autoplay hands the SOUL to a bot that reads the patterns for you, a calm way to study a hard attack or just see a fight play out. Every fight also keeps public stats for wins, losses and time on the fight stats page. Beyond the battles there is more: Dark World Survivors, a survival mode; Spell Card Rush, a bullet-hell gauntlet; MANIA, a rhythm game; blackjack; a Tetris variant played inside the battle box; and DARKDLE, a daily DELTARUNE word game. puskevi launched the simulator on September 30, 2026 and still maintains it alone. It is a beta, so the occasional bug is expected, and there is a Discord for reporting them. It runs in any modern browser, with touch controls on phones, a gamepad mode and keyboard controls on desktop. DELTARUNE Fight Simulator has nothing to do with football. This page embeds the simulator from the developer's own site and hosts nothing. DELTARUNE and UNDERTALE are © Toby Fox. Free to play, no download, no account.
