About PuzzleVault

A small collection made for playing

PuzzleVault brings together two original 3D adventures and ten puzzles based on numbers, patterns, colors and spatial decisions. Start without an account or app installation. Short puzzle rounds sit alongside longer journeys with checkpoints, daily challenges and progress saved in your browser. The English learning room adds guided reading and short practice courses with Korean explanations.

Choose your kind of challenge

NumVault asks you to deduce a hidden code. PatternPop tests recall of a displayed sequence. QuickCalc offers timed arithmetic, including a 30-second friend challenge. GridSmash, MergeChain and HexMatch reward careful placement and combinations. SortStack, TileTurn, ColorFlow and PipeLink offer step-by-step spatial puzzles. Each game page explains its rules, controls and available modes. Mosslight Wardens adds a forest action RPG: plant healing light gardens, restore beacons and choose upgrades. Cloudweft Passage is a 3D platform adventure where changing between sun and moon reveals different bridges between floating islands.

English, one passage at a time

PuzzleVault English brings the Little by Little Reading Room into this collection. Read selected English passages alongside separately prepared Korean translations, word meanings, sentence breakdowns and grammar examples, then practise with questions, writing, device speech and review cards. The interface and explanations are in Korean; the reading text is in English.

English Quest turns the material into short courses using word meanings, sentence ordering and comprehension questions. Daily-course XP is separate from game XP and is a record of practice, not a language qualification. See the reading guides before opening a lesson, and check each work’s sources and usage scope. Existing records from study-english2.pages.dev move through an exported JSON backup and a confirmed import, not an automatic account transfer.

Records that belong to your browser

Finished rounds earn experience toward local levels and badges. Three daily missions reset at midnight UTC. Your scores, settings and progress are stored in this browser; they are not an online account or a verified public leaderboard. Clearing site data, switching browsers or using another device may start a separate record.

A fair invitation to a friend

QuickCalc challenge links preserve the question seed and a self-reported target score. Players get the same question sequence and answer positions, with a 30-second limit and a three-second penalty for a wrong answer. The challenge does not allow time bonuses or hints. Replaying a course is practice, and shared scores are not independently verified.

How the games are presented

The two main adventures use original low-poly models rendered with WebGL, with depth, perspective and lighting. The ten board puzzles use HTML, CSS and Canvas with raised tiles and shaded pieces. Sounds are generated in the browser. The 3D games require WebGL; graphics speed depends on the device. Touch buttons and keyboard controls are explained on each page.

Editorial care and feedback

Guides explain the games that are actually available. Tips are suggestions for play, not medical or educational guarantees. We revise material when mechanics change or an error is reported. Use the contact page to report a broken level, confusing control, accessibility issue or incorrect article. Reports should identify the game, mode and steps needed to reproduce the issue.
