Inside Crazy Monkey 67
Simple arithmetic, real tactics
Every turn you decide whether to push toward 67 or deny the monkey a clean path — and whether to extend a combo or stop while you're still safe.
One number, two players
The number sits on the table and belongs to both of you. Your card moves it — and hands the monkey whatever position you leave behind.
Combo mode: go wild
×2, ×3 and ÷2 always keep your turn alive, and one in five plus/minus cards carries a combo marker. Chain up to six cards in a single turn.
Hidden information
You see the monkey's hand and the next three draws. What you don't see are its mystery cards — one in four comes face down.
The deck
Six ways to move the number
-
+7
Positive
+1 to +9. The only cards that carry you toward 67.
-
−4
Negative
−1 to −9. Pull back from a bust, or deny the monkey a win.
-
×3
Multiply
×2 and ×3 leap up the board — and always extend your turn.
-
÷2
Divide
÷2 halves the number, rounding to the nearest whole. Extends your turn.
-
0
Skip
Changes nothing and ends your turn. Cycles a dead card out of your hand.
-
?
Mystery
Face down to your opponent until it's played. You always see your own.
How to play
Learn it in two minutes
-
01
Play a card
At least one card per turn. Its effect applies to the shared number immediately, and you draw a replacement straight away.
-
02
Push the combo — or stop
Multipliers, dividers and combo cards let you keep going. The real question is whether continuing is still safe.
-
03
Land on 67
Exactly 67 wins on the spot. Overshoot past 99 or fall below 0 and you lose immediately — so mind what you leave behind.
Your opponents
Four minds, one target
Pick how hard the monkey thinks. Every opponent plays by the same rules — they just see more of the board.
- Street Monkey Easy
- "Warm up, little human." Plays without a plan and misses winning moves. Good for learning the game.
- Mad Scientist Medium
- "Getting harder now." Takes obvious wins and avoids handing you easy ones. Makes the occasional mistake.
- Death Monk Hard
- "You'll need more than luck." Plans two moves ahead and shuts down your combo setups before they land.
-
Ancient Oracle Expert
- "Only the insane prevail." Calculates every winning sequence from both sides and almost never gives you an opening.
