Lost Ruins of Arnak is a worker placement and deck-building hybrid game for 1–4 players set on a mysterious island of ancient ruins. Designed by Mín and Elwen (Czech Games Edition, 2020), it combines the resource chain of worker placement with the card cycling of deck building, adding an exploration track and artifact research layer that gives it a distinctive archaeological adventure flavor. Players lead expedition teams excavating sites, fighting guardians, acquiring items and artifacts, and advancing up the research track — the game's central source of victory points and ongoing bonuses. Arnak plays in 30–120 minutes depending on player count and is widely praised for its satisfying combination of mechanics and thematic coherence.
How to play
Setup: Place the main board showing the island map (with face-down site tiles), research track with assistants, and supply rows for cards and artifacts. Each player starts with the same 5-card deck (2 Compasses, 2 Tablets, 1 Jewel) and 2 workers. On your turn, take one action: - Dig at a new site: Pay the compass cost shown and place a worker on a new site tile (flipping it to reveal its resource reward and guardian). Gain the site's resources. OR, if the site has a guardian, you must defeat it by paying the shown resource cost — if you can pay it, the guardian is removed permanently and you gain a bonus. If you cannot pay it, you may still dig without defeating, leaving the guardian present. - Dig at an existing site: Send a second worker to a site already excavated (without a guardian) to gain its resources again. - Discover an artifact: Pay the compass cost of the artifact row and acquire that artifact card. - Buy a card: Spend resources shown to buy an item or artifact card into your discard pile. - Play a card from hand: Place a card from your hand into your play area to gain its effect (resources, workers, research track movement). - Research: Move your researcher pawn up the research track by paying the shown cost — gain the bonus shown at each step and at end-of-track positions. Scoring: At game end, total VP from your research track position (largest source), artifacts in your deck, items purchased, guardians defeated, and the final research idol.
Strategy
Lost Ruins of Arnak rewards players who advance the research track aggressively, since it is the game's largest VP source and also provides ongoing bonuses that compound through the game. Research track is the priority: Moving up the research track costs resources but earns both points and powerful assistant bonuses at certain positions. Players who reach the top of one branch score 14+ points from the track alone — roughly half the winning score in a typical game. Commit to a research path early (the track splits into three branches, each with different bonus types) and push it consistently. Deck quality over deck size: Like Dominion, a smaller, more powerful deck cycles faster. Avoid buying weak items just to have more cards. The best Arnak decks contain 8–12 high-quality cards that reliably generate the resources needed for research and site exploration. Card and artifact synergies: Artifact cards provide ongoing effects when in play (not just when drawn). Some artifacts generate extra resources each time you dig at a site; others trigger when you play specific card types. Building your deck around two or three synergistic artifacts can create powerful resource chains. Research path bonuses also interact with specific card types — match your research path to your deck's card types. Site selection strategy: Each excavated site provides different resources and guardian difficulties. Sites with valuable resources (compass + tablet) are worth fighting for even with tough guardians. Sites near the end of the exploration zones provide bonus resources. Control the most resource-rich sites by exploring them before opponents, then revisiting with a second worker. Tempo vs. engine: An early research push (spending resources on the track) is tempo-efficient but resource-hungry. A card-buying focus builds a stronger engine for later turns. Most winning games balance both — strong card acquisition in rounds 1–2, then sustained research in rounds 3–5.
Tips
- The research track is the game's biggest VP source — push it every round, not occasionally. - Defeat guardians when you can; the rewards are significant and clearing a site lets teammates use it freely. - Buy assistants from the research track early — they provide free resources on every turn and compound throughout the game. - Don't over-buy cards; a tight 8-card deck that cycles every 2 turns is more powerful than a 14-card deck with weak filler. - Artifacts in play provide ongoing effects — prioritize artifacts that synergize with your planned research path. - Compass cards (movement resources) are scarce; protect them from being overcrowded out of your hand. - The game ends after 5 rounds — plan your research track position on a per-round basis and don't fall behind in round 3. - Guardians left on sites block your second-worker actions there; clear them early or route around them.
Player count & time
1–4 players in 30–120 minutes (shorter at 1–2, longer at 3–4). The solo mode is highly regarded. At 2 players the game is the most strategic; at 4 players site competition becomes fierce and planning is harder.
Expansion: Expedition Leaders
Adds six asymmetric leaders, each with a unique starting deck, special ability, and different starting resources. Dramatically increases replayability and adds meaningful strategic differentiation between players from the start.
Why it works so well
Arnak's hybrid of worker placement and deck building avoids the "analysis paralysis" of pure worker placement while adding more planning depth than a pure deck builder. The archaeological theme is coherent and the research track gives every game a clear arc.
Common beginner mistake
Ignoring the research track to focus on card buying, then scoring 8–10 fewer VP than opponents who pushed the track consistently. Research track advancement is not optional — it is the game.
