Tagline: One tap. One tower. One winner a day.
Subdomain: stack.silentinfinity.com
Reverse-engineered from: Stack/Helix Jump (one-finger hypnosis) + Solitaire Cash (skill-based real-money tournaments).
Why it's not gambling: outcome is determined by player skill (timing precision), not chance. Same legal posture Solitaire Cash uses to operate in 45+ states.

> STACK launches the world's first one-tap precision tower with a daily $500 prize purse.
>
> San Francisco — May 7, 2026. Today STACK opens its first daily tournament. Stack a tower of glass-and-neon blocks with a single tap; the higher and tighter the stack, the higher you climb the daily leaderboard. Top three split the prize pool. Entry is $1. Today's pool: $487, and growing every minute.
>
> STACK pairs the hypnotic, one-finger gameplay that made Stack/Helix Jump category-defining with the appointment-tournament model proven by Solitaire Cash. Every run is 60 seconds, every run earns a portable ELO rating, and every run produces a shareable scorecard your friends can directly challenge.
>
> "We don't sell pay-to-win," says the STACK team. "We sell precision. Buy a marble skin if you want to look good losing — your tower height is yours alone."
How long is one game? 30–90 seconds. The block speeds up every level.
How does the tournament work? $1 entry. Best single run between 00:00 and 23:59 UTC counts. Top 3 split the pool 50/30/20.
Is this gambling? No — outcome depends entirely on tap-timing skill. No randomness in the core mechanic. Same model as Solitaire Cash / Skillz games.
What if I miss? The overhang is sliced off. Smaller block next round. Miss completely → tower collapses, run ends.
What carries between runs? Your ELO ("Skill Rating"), cosmetic skins, Lucky Saves, Pro membership. Not money or score.

Innovative hooks (the "novel angle" the brief asks for):
1. Cross-game portable ELO. Your skill rating follows you when GAUNTLET expands — a Bronze III in STACK is a Bronze III everywhere. This makes the rating itself a sunk-cost moat that no competitor can replicate without a hub.
2. Lucky Save at the precise moment of failure. The paywall hits the one frame a player would pay anything to undo — not a pre-emptive ad, not a generic continue. It is the single most psychologically loaded $0.99 in mobile gaming.
3. Variable-pool prize transparency. The pool is shown live, increases visibly with each entry, and the share card includes "today's pool" — turning every share into a recruiting poster for the tournament itself.
