Beacon Lattice
Cover every cell. Overlap nothing.
An exact-cover lattice invented for NoCharge: place beacons so every cell is covered exactly once, with a solver-backed puzzle set and a documented forced-move deduction system.
Reviewed collection
Originals Only
NoCharge games whose rules are not a named third-party title: custom mechanics, original art, honest limits.

Inclusion method
Include a current game when its ruleset is not a named third-party game clone and the implementation is NoCharge's own design — verified against the game catalog's isOriginal field, which is a factual classification, not a quality claim.
These are the games NoCharge designed rather than reimplemented. They are not necessarily “better” than the classics — the classification says where the rules came from, not how good they are.
Why this collection exists
NoCharge ships both classic rules (Klondike, Nonogram, Sudoku) and originals. This collection separates the two so readers can find the custom designs without assuming the classics are clones of a specific brand — and without assuming originals are superior.
How we decide inclusion
- The ruleset is not a named third-party game: no clone of Wordle, Spelling Bee, 2048, or any trademarked title by name or trade dress.
- The mechanics are implemented first for NoCharge, with original naming and art.
- The catalog’s
isOriginalfield is true and the classification is reviewed with each catalog change.
Twenty Forty-Eight is excluded: it is NoCharge’s original implementation of a well-known 2048-style merge, but the rules are not NoCharge’s.
What you will find in the grid
Each card shows genre, session length, and the rule-set fact that qualifies it. Originals also carry a stronger guide and at least one systems article explaining how the mechanic differs from familiar games — see Beacon Lattice’s exact-coverage article and Color Flip’s visual-versus-turn-based article.
Limits
- Original does not mean free of influence; mechanics can be inspired by familiar puzzles.
- Original does not mean tested-with-you or medically beneficial.
- NoCharge does not claim novelty protection; this is a factual editorial classification.

Color Flip
Pick a color. Step carefully. Take your time.
A color-cycle stepping game with a moving visual mode and a deliberate turn-based reduced-pressure mode — the color state and both modes are NoCharge's own design.
Tile Garden
Plant seeds. Grow flowers. No rush.
A garden merge game where seeds grow through tiers into flowers, with no timer and merged tiles replaced by the next plant rather than a score chase.
Word Tile Rush
Spell words. Clear the grid.
A rising word grid where letters climb and words are submitted with a documented scoring formula; preserved timing, but the grid mechanics are NoCharge's own.
