Tide Oath

Draw an adjacent chain of three or more equal sigils, then Release. A chain of four earns a tide charge. Wash a reef bordering your most recent chain to expose its hidden sigil and reconnect the broken Kelp or Coral row. Clear both reefs and all sigils within eight releases. Cancel redraws a chain without spending a turn.

Tap controls, or Tab then Enter/Space. R restarts. Every action is turn-based; take time to plan.

Explicit chain drawing and deity-like obstacle-clearing assistance.
