The
Bin-Esta™
Challenge
An office World Cup, invented by Sunstall. One ball. One bin. Five rounds. One champion of the solar industry.
Invented by Sunstall.
Built by the international team at Sunstall Inc, California to celebrate the upcoming FIFA World Cup hosted across Mexico, Canada & the U.S.
Bin-Esta™ — a wordplay between bin and fiesta — is a 5-round office tournament that crowns the sharpest shooter in solar. Pair it with our Suncup Prediction Challenge and bring the World Cup energy straight to your warehouse, rooftop, or office floor.

The Goal (Bin)
Scorecard
Mark the Pitch.
The Target Corner
Bin snugged into a 90° corner. Both intersecting walls must stand at least 23.6 in (60 cm) to enable strategic bank shots.
The Shooting Mark
One fixed spot on the floor: 47.2 in (120 cm) wide of the corner, 98.4 in (250 cm) away from it. All shots taken from here — no cheating forward.
Why The Corner?
Tight angles + bank-shot geometry = skill, not luck. Every wall bounce is fair game.
The Rules.
Turns
Every player gets 6 consecutive attempts per turn.
Execution
All 6 shots taken strictly from the designated shooting mark.
Match Length
A full tournament is 5 rounds — spread across a week if you like.
Scoring
Ball lands inside the bin = 1 Hit. Miss = 0. Simple.
Champion & Tie-Breaker.
The Champion
Highest total Hits across all 5 rounds wins the tournament and the eternal bragging rights of the Sunstall office floor.
Sudden Death
Tied at the end of round 5? Step back to the mark. Shootout until one player stands.
