9 Kings: How to Reach Year 100 With Spacetime and Rainbow Perks

To reach Year 100 in 9 Kings, pair the economic compound interest from Spacetime acceleration with universal Rainbow perks, while investing excess gold directly into board deployment slots rather than shop rerolls. Year-skipping rapidly inflates enemy stats and cuts down the number of draft phases you receive, so your board must prioritize cross-faction buffs and sturdy crowd control before you push past mid-game milestones.

How Spacetime Acceleration Changes Combat Scaling

Accelerating years with Spacetime mechanics triggers interest payouts and skips early filler battles, but it drastically reduces your opportunities to fine-tune unit formations.

Hostile armies scale exponentially in health and damage every decade. If you advance kingdom time without verifying that your current damage per second can clear immediate milestone bosses, a defense that easily cleared Year 40 can fail instantly at Year 60.

To maintain run stability:

• Check your damage output and crowd control strength before activating any further year skips.
• Never trigger year advancements if your frontline takes heavy structural damage or loses units during standard wave clears.
• Treat the skipped years purely as an economic engine, not as an excuse to neglect board capacity.

Drafting Rainbow Perks for Cross-Faction Synergy

In Update 0.9, Rainbow perks expand your draft flexibility by providing universal baseline bonuses that do not depend on narrow faction tags. Because Spacetime acceleration reduces total draft phases, waiting for specific tribal synergies—such as pure Blood, Spells, or Nomads—wastes critical turns.

Rainbow perks apply global attack speed, raw damage amplification, and survivability buffs to all active board slots. This universal coverage allows you to recruit high-tier neutral units, legendaries, or mercenary powerhouses into your army without breaking existing synergy thresholds.

Managing Gold and Trimming Your Deck

Spacetime progression generates massive compound gold from interest thresholds. The primary pitfall during accelerated runs is spending this gold on rerolling the shop for specific cards.

Instead, allocate your capital using these rules:

1. Purchase deployment slots first: Increasing your unit cap provides immediate board power and allows you to absorb enemy charge impacts.
2. Upgrade unit ranks directly: Invest gold into leveling your established frontline and carry units to their maximum tiers.
3. Thin your deck: Actively remove low-tier starter units and obsolete early-game perks. Keeping your active pool small ensures that essential crowd control abilities and area-of-effect spells appear reliably during combat.

Navigating Late-Game Decades to Year 100

Enemy compositions in the final push feature heavily armored champions backed by swarms of support troops. Adjust your progression and placement through each distinct phase:

• Years 50–70: Consolidate your primary damage carries, secure at least two core Rainbow damage perks, and equip your frontline with active shielding or self-sustain perks.
• Years 70–90: Stop all optional time skips if your board health fluctuates. Use these normal turns to finalize deck cuts, purchase remaining unit slots, and max out unit ranks.
• Years 90–100: Offset your durable tanks slightly forward to absorb initial charge attacks away from your damage dealers. Spread ranged carries across separate lanes so elite boss cleave attacks cannot wipe out your backline simultaneously.
