V0.351 · LIVE RULE FEEDBACK · EXACT LOGIC

Tents & Trees

Pair one tent with every tree, satisfy every edge count, and never let tents touch. The board stays central with live rule feedback, fast grass marking and exact hints that teach a forced move without silently playing it for you.

Practice setup
Campaign stays fixed at 60 exact-unique boards. Practice generates repeatable boards locally and accepts only candidates with exactly one solution; the frozen bank remains a fallback safety net.

Tap cycles blank → tent → grass. Desktop: right-click or right-drag paints grass. Keyboard: arrows move, Enter/Space cycles, G grass, H hint, Ctrl/Cmd+Z undo.

Rules, exactness & hint contract

One tent per tree. Every tree pairs one-to-one with an orthogonally adjacent tent. No touching. Tents may not touch horizontally, vertically or diagonally. Edge counts are exact. Every row and column must match its number.

All 60 campaign source boards come from the frozen bank and are solver-verified unique. Hint first searches named human deductions from the V0.221 lab; if none is available, it uses an exact continuation test and highlights a forced cell. Asking for Hint, Check or Auto Grass marks the run Assisted; Undo and Restart do not.

Exact Deduction & Repeatability Lab

Train the deductions that actually solve Tents & Trees: close completed lines, spot lonely trees, fill tight lines, propagate tent exclusion and use one-to-one pairing bottlenecks. Every drill is derived from a solver-verified unique source board.
