スライディング15
30の保存ステージから選び、クラシック・蛇行・列・アンカー・迂回の目標に挑戦します。
世界とミッション
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.
ゲームの仕組み
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.
ステージ6以降、空きマスは直前の移動をすぐに逆戻りできません。 ステージ16以降、印の付いたアンカータイルは動きません。
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.
遊び方
- 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.
- ステージ6以降、空きマスは直前の移動をすぐに逆戻りできません。 ステージ16以降、印の付いたアンカータイルは動きません。
- 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.
攻略のヒント
- 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.
進行と難易度
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).
ステージ6以降、空きマスは直前の移動をすぐに逆戻りできません。 ステージ16以降、印の付いたアンカータイルは動きません。
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.
開発者メモ
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.
