Continue your kingdom after victory
After defeating the final invasion in year 33, choose to continue your kingdom into Endless Mode. Keep it growing through repeatable card effects and ongoing buffs once normal upgrades run out.
Event cycles continue, and the Tower becomes permanently available for purchasing extra plots. Final battles return at 33-year intervals, beginning in year 66. Treat victory as the point to check whether your kingdom can keep improving, rather than proof that its current damage will last forever.
Choose growth your kingdom can sustain
Most ordinary structures stop at level 3 unless an exception changes their limit. Before continuing, identify what improves your kingdom after those upgrades are exhausted: adjacent level-up chains, annual buffs, allied deaths, sacrifices or cards thrown into the pit. Build around a trigger you can keep supplying.
Your chosen king determines your starting deck, but attacking rival kings lets you loot cards from theirs. Use that access to fill a specific gap in your engine. A support card that strengthens your existing layout is usually a clearer investment than starting another unrelated plan.
Enter endless play and prepare for its timeline
- Defeat the final invasion in year 33. Winning that battle reaches the point where you can extend the kingdom beyond the normal run.
- Choose to continue the same kingdom instead of ending the run. This carries it into Endless Mode, where attacks and event cycles keep coming.
- Purchase an extra plot through the permanently available Tower when your engine needs room. Give the space a job before buying it, such as holding support, fodder or a movement destination.
- Prepare your defenses for the next final battle in year 66. Further finals recur every 33 years, while recurring champions and increasingly demanding fights keep testing the kingdom between milestones.
Choose an engine with room to grow
| Engine | Details |
|---|---|
| Lab Rat upgrade chains | Place Lab Rats beside plots you can keep levelling. Lab Rats have no maximum level and automatically level when an adjacent plot does. Patronage also triggers their chain effect, giving that card another use in a kingdom built around upgrades. |
| Recycler discard growth | Put a Recycler beside valuable plots, then throw spare cards into the pit. Each discard gives adjacent plots +2% damage and HP per Recycler level. The engine depends on a continuing supply of cards; an empty hand leaves it with nothing to trigger. |
| Mangler sacrifice growth | Keep a Mangler touching a stocked troop plot. It sacrifices an adjacent unit each year to gain lasting damage and HP, while its meat trolls carry the fighting. Replenish the fodder: a year with nothing beside the Mangler is a year without that growth. |
| Demon Altar and Bombers | Place Demon Altars early while Bombers clear waves. Allied deaths permanently strengthen the Altars, and Bombers contribute when they explode. This prepares a handover: when blasts stop clearing enemies, the demons have accumulated strength behind them. |
| Annual support-building buffs | Keep Blacksmiths, Forests or Beacons touching the plots they should improve. Their annual buffs provide growth beyond ordinary upgrades: Blacksmiths add damage, Forests add HP, and Beacons add attack and movement speed. Placement determines which plots receive the benefit. |
| Treant levels through Patronage | Raise the Treant to level 3 normally before using Patronage. Patronage then adds 3 base levels beyond the normal cap, and Rewind can supply further copies. Patronage is a Rainbow card, so commit to this route when it actually becomes available. |
Keep upgrades useful after ordinary caps
Use the upgrade route that fits the cards already doing useful work. Raising a limit creates more room to grow, but you still need a way to deliver the upgrades.
- Choose Futurism for a troop-level strategy. It allows troops to reach level 99, extending their upgrade path while still leaving a defined ceiling.
- Choose Speculation when Vaults support your economy. Vaults automatically level each year, and Speculation raises their level cap to 99.
- Cast Regression on an upgraded Demon Altar to lower its level without losing its accumulated stats and effects. Regression cannot be played on level 1 plots.
- Play another Demon Altar copy onto the regressed plot. Levelling it again adds another demon while retaining the strength the Altar already earned.
- Use X-Ray when you need an upgrade effect that works beyond maximum level. It provides another route past an ordinary cap without making every other levelling effect limitless.
Recognize when an engine stops paying
A Shrine can fail when every plot is maxed out. More random levelling is then less useful than an effect that can still change your kingdom. Check the upgrade preview before spending a valuable card; it shows which stats or effects would increase.
Keep landing space open if you use Camps with Migration or Dwarfs. Camps trigger when a card lands on an empty plot, and Migration requires an empty adjacent destination. Filling every available space can choke the movement pattern that feeds those buffs.
Watch what the enemy prevents your damage from doing. Steel Coat cancels opening hits, which is especially awkward for a Bomber that only gets its explosion. Enemy Warpers create a different problem: they keep summoning, while a trap field can eventually run out of traps.
Keep a long run manageable
Very large armies can strain performance. Use Disable battle FX to reduce battle effects, and Fast UI animations for quicker interface transitions. Disable building animations is another available option when you want less animation on screen.
The PC full release arrived on November 12, 2026, with large-army performance improvements and an increased gold cap. Older Early Access cap figures should not determine your investment decisions. For the launch update, start a fresh run after patching: existing runs do not store its changes and may cause conflicts.
