Bingo Sprint

Bingo Sprint runs a 90-second countdown. Numbers from 1 to 75 are called one at a time on a 2.5-second cadence; around 36 land in a full game. When the clock hits zero the game ends, regardless of how many cells remain undaubed.

Daub scoring is speed-sensitive. A valid daub always earns 100 base points, and every second of delay costs part of a 100-point speed bonus. Daub within 1 second for a perfect mark: at least 150 total and better meter fill. Wait 2 full seconds and the speed bonus is gone entirely. Those 2 seconds are where the format's skill ceiling sits.

The boost meter fills on every valid daub: 35% for a normal daub, 75% for a perfect one. Filling it queues one of four boosts (Free Daub, Golden Ball, Time Boost, or Double Points) in a stack that holds up to three. Time Boost adds 10 seconds to the clock. Double Points doubles daub and bingo income for 10 seconds. Golden Ball lets you pick from four uncalled numbers on your card and daub one with normal scoring. Free Daub marks any cell on the card with no points or meter fill.

Bingo patterns are not claimed automatically. Pressing the Bingo button claims all pending patterns at once for 1,000 points each. Thirteen patterns are available: five rows, five columns, two diagonals, and the four corners. The center square is always the free space, so any pattern that runs through it needs only four other cells daubed. A false bingo claim costs 100 points.

Bingo Sprint runs the same scoring engine used to build the strategy guide. The 90-second format rewards specific habits: scanning the card in a fixed order, claiming completed patterns without false calls, and sequencing boosts without losing the next number. Seeded call sequences make practice comparable: replay the same card and calls, change one habit, and measure the result.
