Puzzle 15 scorrevole
Scegli tra 30 fasi salvate con obiettivi classici, a serpentina, per colonne, con ancora e deviazioni.
Mondo e missione
The campaign starts with fifteen numbered tiles and one empty space, then opens six authored arcs: Open Corridors, Zigzag Gallery, Column Workshop, Anchor Workshop, Detour Circuit, and Crown Circuit.
Every stage asks you to preserve access while building a distinct target arrangement. Checkpoints at stages 5, 10, 15, 20, 25, and 30 mark the end of each five-stage arc.
Sistemi di gioco
A tile moves only when it shares an edge with the empty space. Diagonal moves, jumps over another tile, and swapping two occupied tiles are not legal.
Dalla fase 6, lo spazio vuoto non può invertire subito la mossa precedente. Dalla fase 16, la tessera ancora contrassegnata resta ferma.
Complete a stage to save it locally and unlock the next stage. Hint marks one legal candidate without moving it; Undo restores the prior board and move count; Result offers Replay, Stages, or Next Stage.
Touch, mouse, and keyboard-friendly controls use the same board state. No timer, account, purchase, or network service is required; locale and sound preferences stay in this browser.
Come si gioca
- Choose Start Game from Main, then select an unlocked stage from the 30-card Stage screen.
- Read the arc rule and target pattern before sliding a neighboring numbered tile into the blank.
- Dalla fase 6, lo spazio vuoto non può invertire subito la mossa precedente. Dalla fase 16, la tessera ancora contrassegnata resta ferma.
- Use Hint when you want one legal candidate, and Undo to compare a route or recover from a closed corridor.
- Match the stage target to complete it, save your progress, and use Result → Next Stage or Stages to continue the campaign.
Consigli strategici
- Work from the next target number, but do not trap the blank behind a row or column you still need.
- Keep more than one route to the next target when possible; a legal move can be safe now but harmful two moves later.
- Use the bottom row and right column deliberately because the final placement needs room for the blank.
- When the board feels stuck, use Undo to return to the last position with more open neighbors instead of guessing.
- Compare Hint with your own plan—the hint explains a legal option, not a mandatory solution.
Progressione e difficoltà
The 30 selectable saved stages are arranged as six arcs of five: Open Corridors (1–5), Zigzag Gallery (6–10), Column Workshop (11–15), Anchor Workshop (16–20), Detour Circuit (21–25), and Crown Circuit (26–30).
Dalla fase 6, lo spazio vuoto non può invertire subito la mossa precedente. Dalla fase 16, la tessera ancora contrassegnata resta ferma.
Every fifth stage is a checkpoint. Completing a stage unlocks the next one, while local progress keeps cleared stages available for replay and move-count improvement without a timer.
Nota di design
Sliding 15 uses the shared Classic Logic Lab shell, a responsive 4x4 board, a 30-stage authored campaign, stage-specific target rules, local progress, touch/mouse/keyboard input, localized Hint and Result feedback, reversible Undo, and an explicit Main-Stage-Battle-Result recovery path.
