Card types
Strain Cards
Combat cards. The backbone of your deck. Two stats:
- Attack — How hard it hits when invading
- Defense — How well it holds ground
- Stats range from 1 to 8
Claim empty territories, reinforce holdings, launch attacks.
Event Cards
One-time effects that shift the board in a single play. Resolve immediately during your Action Phase.
- Draw extra cards
- Steal from opponents' hands
- Destroy a territory's defender
- Claim any territory outright — no combat
Events reward patience. Save them for the moment that changes the game.
Instant Cards (Online only)
Response cards. Played during other players' turns, not yours.
- Boost combat stats mid-fight
- Cancel an incoming attack
- Counter Events before they resolve
Playing an Instant never costs your action. You can play multiple in a single interrupt window.
Turn structure
Five phases. Same order every turn.
Phase 1: Territory
Your territories activate automatically. Collect the benefit.
Control Sativa Springs? Draw one extra card before anything else.
Phase 2: Action
The heart of your turn. Choose exactly one:
Claim Territory
- Play a Strain onto an empty territory. It's yours.
Attack
- Play a Strain onto an enemy territory. Combat resolves.
Play Event
- Fire an Event card. Effect resolves immediately.
- Online: opponents get a brief window to respond with Instants.
Skip
- Discard one card and pass. Use sparingly — skipping is falling behind.
Playing an Instant never counts as your action. You can play Instants during opponents' turns and still take your full action on yours.
Phase 3: Combat
If you attacked, combat resolves here. See Combat System below.
Phase 4: Draw
Draw up to your hand limit.
Phase 5: End
Check victory conditions. No winner? Next player.
Combat system
The mechanic you need to understand precisely. One misread here costs games.
How it starts
Play a Strain from your hand, target an enemy territory. That triggers the sequence.
The sequence
Step 1. Attacker plays their Strain and declares the target.
Step 2. (Online only) Interrupt window opens. Any player can respond with Instants.
Step 3. Compare stats. Attacker's Attack vs. Defender's Defense. Multiple defenders (CBD Coast)? Sum their Defense.
Step 4. Resolve.
| Result | What happens |
|---|---|
| Attack beats Defense | Attacker takes the territory. Defender's card discards. Attacker's card stays. |
| Defense beats or ties Attack | Defender holds. Attacker's card discards. |
| Exact tie | Dice roll (0-100). Higher wins. Dice also tie? Both cards discard, territory goes empty. |
Combat modifiers
| Source | Effect |
|---|---|
| Indica Island | +2 Defense when this territory is being defended |
| CBD Coast | Stack 2 defenders (Defense values add) |
| Potent Power Up (Instant) | +3 Attack this combat |
| Buckle Up Buckaroo (Instant) | +3 Defense this combat |
CBD Coast's two defenders stack their Defense values. Indica Island's +2 applies when Indica Island itself is under attack. Together they make those two territories the hardest positions on the board to break.
Hand management
Starting hand: 3 cards Max hand size: 7 cards Required: Play or discard at least 1 card every turn
Over 7 after drawing? Discard down. Running low means you can't respond. Running full means you're not using what you have. The sweet spot is 4-5 cards with a mix of options.
Reinforcing territories
You can play additional Strains onto territories you already control:
- Most territories: 1 defending card max
- CBD Coast: 2 defending cards (its unique ability)
Multiple defenders? Sum their Defense. A 3-DEF card plus a 4-DEF card equals 7 total.
Discarding
Discarded cards go face-up. A few Events can retrieve from the discard pile. Know what's there — it informs how you use those Events and what your opponents might recover.
Victory conditions
Primary: Territory Control
When the final card is drawn, one full round remains. Every player takes a complete turn. Then count territories.
Most territories wins.
Tiebreaker
Tied on territory count? Most cards in hand wins.
Instant win: Domination
Control all 9 territories at any point during your turn. Game ends immediately. You win.
Rare. Opponents will attack specifically to prevent it. But with the right setup and timing, it happens.
Bonus victory points
Three territories add to your count at game end:
| Territory | Bonus |
|---|---|
| Ganja Grove | +1 VP for every turn you held it |
| THC Terrace | +1 VP per Strain card in your hand |
| Dank Desert | +1 VP per Event card in your hand |
These swing close games. They reward specific strategies and often decide the final count.
Event timing
Events resolve immediately. In online mode, an interrupt window opens after you play one — opponents holding Federal Intervention can try to counter.
Play your big Events when opponents are low on cards or have already burned their Instants.
Online vs. local
| Local | Online | |
|---|---|---|
| Instant Cards | Not included | 10 cards added |
| Interrupt Windows | None | 10-30 seconds after each action |
| Deck Size | 68 cards | 78 cards |
| Real-time Response | No | Yes |
Online adds genuine counter-play. Every action can be responded to. Every opponent's action is your opportunity. That changes how you value Instants and how you time Events.
