क्लासिक, सर्पिल, स्तंभ, एंकर और डिटोर लक्ष्यों वाली 30 सहेजी गई अवस्थाओं में से चुनें।
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.
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.
चरण 6 से खाली स्थान पिछली चाल को तुरंत उलट नहीं सकता। चरण 16 से चिह्नित एंकर टाइल स्थिर रहती है।
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.
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).
चरण 6 से खाली स्थान पिछली चाल को तुरंत उलट नहीं सकता। चरण 16 से चिह्नित एंकर टाइल स्थिर रहती है।
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.
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.
Sliding 15 is a general-audience browser puzzle. No account or purchase is required; cleared stages, settings, and local progress stay in this browser and may be removed when site data is cleared.
