About House Party
House Party: Jump-In + Last Card Call + Doubles + 7-0 + stacking. House Rules tables are new on the website: the table rules people argue about at home, built into the engine so nobody has to referee.
The table
4 players: you and 3 computer rivals. Everyone starts with 7 cards.
Sharp rivals shed high-value cards first, save their wilds for the end and keep the colour they hold most of alive. They are the standard opponent.
The deck
The table uses the 126-card Prism deck: numbers 0–9 in four energies (Flare ▲, Surge ●, Volt ◆, Void ■), two each of FLIP, FREEZE, +2, SHIELD and SWAP per energy, 6 PRISM wilds and 4 +4 wilds.
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 with cross-stacking: answer any +2 or +4 with another draw card — including a +4 on a +2 — and the whole pile moves on to the next player.
- SHIELD cards stay in front of you and block the next draw attack aimed at you, however big it is.
- The Riot Meter charges with every card you play; combos charge it faster. At 100% hit RIOT BURST to shatter up to 2 number cards of the active energy at once.
- Play a 7 and you swap your whole hand with any rival you choose.
- Play a 0 and every hand rotates one seat along the direction of play.
- Jump-In: if you hold the exact same card as the top card — same energy, same symbol — slam it down out of turn. Play continues from you.
- Last Card Call: when you go down to one card you must press LAST CARD. Forget, and anyone can catch you before the next play — you draw two. Catch rivals who forget!
- Doubles: play every number card of the same value in one move. The first must be legal; the last one you lay sets the energy.
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 House Party
- Watch the top card on every turn. Identical cards glow gold when you can jump in — it steals the turn order and can skip a rival about to win.
- Call LAST CARD before you play your second-last card — then nobody can catch you. And keep an eye on rival hands: a ❗ means they forgot.
- Hoard pairs. Two or three of the same number shed in one move and charge the Riot Meter for each card.
- A 7 is a comeback card: hold it until your hand is bigger than a rival's, then swap with whoever has the fewest cards.
- Charge the meter with combos. Several plays in a row fill it faster; burst when it shatters your highest-point number cards.
- Play a SHIELD early when your hand is large — it waits in front of you and eats the next +4 or +10.
