Overhaul

How players use it

• King of Nothing Enemies: avoid Blood, whose Bombers break the front line, and Stone where possible. Fight Progress early for Overhaul. Three independent players call Nothing the most consistent king; the Castle plan has three sources and the troop plan two.
• How to beat King difficulty and King IX IX in 9 Kings Six guides and forum threads written between July 2025 and November 2026 describe the same plan for King and the King IX levels. Fill the perk board before the run, especially with early-game and multiplier perks. Pour every level and buff into one carry, either your base or a single troop plot. Keep your free re-rolls for the decree that powers that carry at the year-5 Royal Council. Re-roll the attacking king to avoid area damage and to collect Overhaul or Offering. Restart openings that cannot reach the carry. Source counts below are independent authors; the plans are checked against 1.0 card text.
• Level-up chains: Lab Rat, Concabulator and Overhaul Lab Rat levels up whenever an adjacent plot levels up, with no maximum level. A level-up next to one Rat therefore levels the Rat too, and if that Rat sits next to another Rat, the second one levels as well. The chain starts from anything that levels a plot: an upgrade, Wildcard, Overhaul, a level-3 Concabulator and, since Patch #29, Patronage.
• What a card does on a plot A troop, building or tower can only be upgraded by the same card. Wildcard, Overhaul, Concabulator and the Gentrify decree also raise levels. Buildings such as Blacksmith and Farm only affect adjacent plots, so a building in the centre of the 3×3 grid touches four plots and a corner building touches two.
• Decrees that act once Hand replacers: Supplies (one copy of each of your king’s cards), Imports (one card from each of the 9 kings), Athenaeum (9 enchantments), Bulldozers (9 Earthworks), Jumpstart (3 Overhauls and 3 Broken Cabulators). They discard the cards you hold, so pick them when your hand is weak or nearly empty.
