Colorado rewards patience and pile organisation above all else.

Core Colorado tips

• Get Aces to the up-foundations and Kings to the down-foundations as soon as they appear — they cost you nothing and free up waste pile space.
• Because each suit needs a card on both the up and down foundation, spreading two copies of the same rank across different waste piles is dangerous.
• With twenty waste piles you can group cards loosely by rank: put high cards together and low cards together so future foundation moves cluster naturally.
• Track which pile received the stock auto-fill — it always adds a new card to an empty slot, so you can plan to clear piles strategically to load up the locations you want.
• Both 2s and Queens are early high-value targets: 2s extend the up-foundation Aces and Queens extend the down-foundation Kings.
• Avoid filling all twenty waste piles early if the stock still has many cards — you need room to manoeuvre.

Key early priority

The best Colorado openers clear Aces and Kings to foundations immediately, then use the auto-fill mechanic deliberately — engineer empty piles in locations that will receive the next stock cards you need, not random slots.

Common mistake

The most common mistake is treating all twenty piles as equivalent and filling them uniformly. This leaves every rank buried under every other rank with no way to sort things out later.
