678KKVault

Shape a path through a shifting ancient ruin in a focused number puzzle. 678KKVault is a short-session strategy game built around one clear action: exchange adjacent rune stones and turn matching numbers into glowing seal nodes. Nodes occupy the board until their path reaches the correct colored gate, so every match is also a space and route decision. Each trial gives you a 6x6 board, 24 moves, three gates, locked tiles, and a moving stone obstacle. Read the board before you act, preserve open corridors, and decide which gate should receive each seal. A careless exchange still changes the obstacle, making order and planning matter more than luck. Use three distinct tools when the ruin tightens: • Etching Powder turns up to two distracting stones into neutral fragments. • The Time Sigil freezes obstacle movement for three effective exchanges. • The Rewind Seal reverses your last exchange and its board change. Complete eight seals before the move limit to finish the Broken Atrium trial. Retry the layout to improve your move count and personal record. The game works offline, requires no account, and keeps progress locally on your device.
