Roundup is a daily puzzle app for people who like a small mental warm-up — and a little nostalgia. Every day you get nine fresh games: PUZZLES • Connections — group sixteen words into four hidden themes • Roundup Word — six guesses to crack a five-letter word • Spelling Bee — build words from seven letters, one required ARCADES • Galaga — lane-based ship arcade with charge shots and bomb power-ups • Breakout — brick smasher with pierce balls and combo cascades • Snake — the classic, with a combo-streak multiplier • Dino Dash — endless runner with four-phase difficulty curves • Round Up Dash — rhythm-tap waveform arcade • Last Stand — split-lane tower defense, fresh seed daily Every game is designed for one or two minutes. Solve a few before coffee. Finish the lineup at lunch. The streaks build over weeks; the daily moment stays small. WHY DAILY GAMES, AND WHAT'S "ROUNDUP"? Roundup is tied to a real, public debt-payoff goal. Every puzzle solved on the web app adds $0.02 toward that goal, tracked in a public ledger. This is a public-accountability mechanic, not a charitable program — Roundup is not a registered nonprofit. The iPhone app does not accept tips or donations. It's a pure puzzle experience; the payoff ledger lives at roundup.day for anyone who wants to follow along. THE DETAILS • No ads. Ever. • No account required to play — your daily plays save to your device. • Optional Sign in with Apple, Google, or email — enables cross-device streaks, leaderboards, and milestone badges (7 / 30 / 100 / 365 days). • Streak freezes: one auto-applied per calendar month, in case life happens. • Ad-free leaderboards, with a four-character disambiguator alongside your display name. • Privacy-first: see roundup.day/privacy for the full policy. We don't track you. We don't sell your data. Five-minute daily ritual. Compound it into a streak. The pot fills itself.
