How to Play SUMMATION™

SUMMATION™ is an equation-building card game powered by two unique mechanics:
Last Card Rule™ and Auto-SUM™.

Use your cards to form valid equations that equal the target SUM of X
discard your cards, and be the first to empty your hand.

Setup:
Each player starts with 7 cards

A shared draw pile
An empty discard pile

Goal:
Be the first player to discard all your cards.

Card Types

Number Cards (0–10)
Used to build equations.
Number Cards placed side-by-side trigger Auto-SUM™

Operator Cards (÷) (×) (–)
Used to form multi-card equations

Wild Operator
Choose any operator: (+) (–) (×) (÷)

Wild Number (0–10)
Choose any number from 0–10.
Cannot be the final card of your winning equation. 🚫 

SUM of X 🎯 

At the start of each round, flip cards from the draw pile
onto the discard pile:
Number cards are added together — Auto-SUM™
Stop when the total reaches 11–20

This total becomes the SUM of X 🎯, the target every player must hit.

Operator cards are returned to the draw pile

Last Card Rule™ (Signature Mechanic)

Every equation must start with the Last Card —
the top card on the discard pile.

This creates a constantly changing equation base and makes every turn dynamic.

Short example:
If the top card on the discard pile is [8],
your equation must begin with:
8 …

Auto-SUM™ (Signature Mechanic)

When two or more number cards are placed side-by-side,
they automatically SUM.

This replaces the need for an addition card and creates powerful combos.

Example:
[2] [1] [4] → Auto-SUM™ → 7

Forming Equations

On your turn, you:

✔ Play an equation

Must start with the Last Card
continue using 1–5 cards from your hand forming a valid equation

✔ Equation requirements

Must equal the SUM of X 🎯
Must follow BODMAS (order of operations)
May use 1–5 cards in any combination
You may use Wild cards

✔ If equation is valid → discard the cards played
Your Last card played becomes the new Last Card for the next player.

🔁 If you cannot form an equation,

draw 1 card and play immediate 2nd chance
Or
draw 1 card and pass

🚫 Wild Number Card cannot be the final winning card

🔁 Drawing Cards

If you cannot form a valid equation:
draw 1 card,
play or pass

⭐ You may choose to draw 1 even if you can form an equation

🏆 Winning the Game
The first player to discard all their cards wins the round.

🚫 Wild Number Card cannot be the final winning card.
