Scalargame is a free set of four daily browser games designed around deduction, ranking, historical intuition, and spatial geography. Each game takes a different mental route, but they share one daily journey, one normalized scoring system, and an optional account for syncing results.
Visitors can play immediately without registering. The landing page tracks today's progress across the four official games and recommends the next unfinished puzzle.
The four games
Scalar — daily country guessing game uses structured clues instead of letter positions. Every country guess reveals signals such as continent, population, area, borders, and distance from the hidden answer. Elements and Cities are available as bonus categories.
Continuum — daily ranking game asks players to place countries in order by population, area, or GDP per capita. Three mistakes end the run, and each wrong answer becomes a useful anchor in the growing ranking.
Whenabouts — daily history timeline game presents five historical events and asks for the year of each one. A draggable timeline supports BCE and modern history, while year-based scoring rewards close estimates without eliminating the player.
Tectonic — 3D geography jigsaw turns real country shapes into playable pieces. The official 60-second Daily grows across a 3D globe; Arcade and Zen add free play, while Regions offers 200 flat geographic puzzles.
One comparable score
The four games have different native measurements: Scalar counts moves, Continuum counts correct placements, Whenabouts awards timeline accuracy points, and Tectonic counts countries placed. Performance Absolute Score (PAS) converts each official result to a 0–1,000 scale without comparing the player with anyone else's run.
| Game | Official daily result |
|---|---|
| Scalar | Countries solved in the fewest moves |
| Continuum | Countries placed correctly before three mistakes |
| Whenabouts | Accuracy across five historical events |
| Tectonic | Countries placed during the timed Globe Daily |
PAS powers the daily total and optional monthly and all-time leaderboards. Practice modes, Scalar's bonus categories, Continuum Elements, Tectonic Arcade/Zen, and the 200 Regions levels stay outside the official four-game total.
Shared product experience
All four games share a responsive React application, a consistent Bench navigation model, daily progress, a sitewide streak, accessible first-use guidance, result sharing, installable PWA behavior, and optional Supabase accounts. Anonymous play remains a complete experience; sign-in adds cross-device result recovery and leaderboard participation.
The first three titles use a paper-like scientific-journal visual system. Tectonic deliberately changes the mood with a dark low-poly ocean, real terrain relief, synthesized sound, and haptics while keeping the same navigation meaning and accessible controls.
Technical architecture
The platform is a React 19 and TypeScript monorepo built with Vite. Each game owns its gameplay code and persistence, while shared modules handle official daily progress, PAS scoring, accounts, result synchronization, analytics, and the PWA shell.
Large content is loaded only when needed. Scalar category datasets are split by subject, Whenabouts puzzles are sharded by month, and Tectonic's Three.js stack plus geography and terrain files are lazy-loaded on its routes. Core assets are precached; large puzzle assets use bounded runtime caching after first use.
Dedicated crawlable explainers at scalargame.com/about, game-specific project pages here, and the Tectonic build story give search engines and AI assistants plain-language descriptions of what each game is, who it is for, and how to play.
