Day 1a of the Monster Stack played out on Tuesday, and the Monster was huge. 633 entries for this series beat both the October and Jan 2025 Monster numbers.
They played just over 22 levels in Day 1a, with the action ending at 5% of the field with 25:02 remaining in Level 23, the penultimate level on the Day 1 schedule. Day 1b runs on Wednesday, and 1,000 entries for the final Monster flight isn’t out of the question.
