About Eights Ruthless
Eights Ruthless: Crazy Eights vs the hardest AI. Classic tables keep the rules close to the card games everyone grew up with, from pure Crazy Eights to long points races.
The table
4 players: you and 3 computer rivals. Everyone starts with 7 cards.
Ruthless rivals read the table: they aim draw cards at whoever is closest to winning, freeze and flip to protect their lead, swap into small hands and fire a Riot Burst the moment it charges.
The deck
The deck is numbers only: one 0 and two each of 1–9 in all four energies (76 cards). There are no action cards and no wild cards — instead every 8 is wild and every 2 makes the next player draw two.
How a turn works
On your turn, play one card that matches the active energy (colour) or the symbol of the top card. Wild cards play on anything and you choose the next energy.
Can't play? Draw one card and your turn passes.
Special rules at this table
- Stacking: answer a +2 with a +2 or a +4 with a +4 to pass the growing pile to the next player. The first player who can't stack draws it all.
How to win
Be the first to shed every card. Your score is 100 for the win plus the points left in your rivals' hands, a speed bonus for quick wins, 25 per Riot Burst, a combo bonus and 50 extra for winning without drawing a single card.
Tips for Eights Ruthless
- Hold your 8s. An 8 is your only way to change the energy, so spend it when you are stuck or to go out, not early.
- This mode trains tactics on your skill radar and pays ×1.3 XP.
