How to play Ravelin
Ravelin is a free online tower defense game. You play in the browser — phone or desktop. Creeps walk a stone path toward your keep. You place towers, spend gold, and hold twenty waves. No download.
The keep
Hearts are lives. A creep that reaches the keep takes one. Gold comes from kills and from calling the next wave with coin still in hand (interest). Pause freezes the line. Undo (Z) takes back a miss-tap.
Towers
Pike is cheap close steel — ground only. Ballista leads bolts, pierces, and hits air. Mortar is slow splash for packs. Frost Lens slows. Sunlance is Keepers Pass. Upgrade damage, fire rate, and range on a selected tower. Sell returns part of the spend.
Waves and maps
Twenty waves, then endless if you still stand. Courtyard is the first yard. Serpentine, Arrowhead, and Nightwell change the fold. A daily trial twists one rule. Flying wisps ignore Pike and Mortar — build Ballista.
Commander ranks
Field XP ranks the commander. The first five ranks are free. After that, cheap Aether shards buy the next rank — on purpose, so a skip feels small. Ranks unlock tower slots and higher upgrades. Rank never decays.
Yards and the board
Sign in (Google, X, or email) to add friends, run a duel, or 2v2 as a separate mode. Queue always fills with a ghost keep. The board is the top 1,000 holds.
