summation

Function

Gain points equal to your current score’s digit sum imes 101

Example

Your score is $123$. You gain $(1+2+3) imes 101 = 606$ points.

multiplication

Function

Multiply your score by the Cell Constant

division

Function

Divide your score by the Cell Constant

division by zero

Function (stand up)

Your score becomes 0, but when another player obtains this Function, your score becomes double what it was before

Example

Your score is $3000$. You obtain this Function, so your score becomes $0$. Next turn, another player obtains this Function, so your score becomes $3000 \times 2 = 6000$.

exponentiation

Function

Raise your score to the power of 0

Rulings

If your score is already $0$, it stays $0$ (rather than becoming $\text{undefined}).

reciprocal

Function (stand up)

Swap scores with another player

Rulings

The other player only needs to tell you their true score once the swap has been finalised.

logarithm

Function

Save your score

Rulings

All your points become saved and your score resets to $0$.

natural logarithm

Function

Unsave your score

Rulings

• Your saved score is added to your current score, and your saved score resets to $0$.
• If you don’t have a saved score, nothing happens.

differentiation

Function (stand up)

Pick the next cell

Rulings

If more than 1 player obtains this Function in the same turn, the extra players are placed on a waiting list to pick the next cell.

integration

Function (stand up)

Pick another player; gain points equal to their score.

partial differentiation

Function (stand up)

Pick a cell to be marked as unused. If multiple players obtain this in the same turn, nothing happens.

Rulings

If a player obtains this Function early on in the game, they are put on a waiting list until there are at least 2 cells they can choose from to undo.

sin

Function (stand up)

Steal another player’s points

Rulings

• You gain points equal to that player’s score, and their score resets to $0$.
• If this Function is reflected by [reflection in y axis], the activator’s points are stolen by the reflector instead.

arcsin

Function (stand up)

Kill another player

Rulings

That player’s score resets to $0$.

tan q

Function (stand up)

Gift another player points equal to the Cell Constant imes 101

secant

Function

Remove the last digit of your score

Rulings

If your score is $0$, nothing happens.

arcsecant

Function (stand up)

Remove the last digit of another player’s score

Rulings

If that player’s score is $0$, nothing happens.

cosecant

Function (stand up)

Pick another player; remove the last digit of their score and insert it at the start of your score

Example

Your score is $271$. You pick a player with a score of $1539$. You remove the $9$, so their score becomes $153$, and yours becomes $9271$.

interpolation

Function

Add 1 to each digit of your score

Rulings

$9$ increments to $0$.

Example

Your score is $9019$. The $9$-s become $0$-s, so your score becomes $0120 = 120$.

extrapolation

Function

Remove all zero digits from your score, then reorder the remaining digits however you like

Rulings

You can choose to keep the order unchanged.

Example

Your score is $12050$. Remove the zeroes, giving $125$. Then you can rearrange your score to $521$, $251$, etc.

translation

Function

Move the first digit of your score to the end of your score

Example

Your score is $69420$. The $6$ moves to the end, so your score becomes $94206$.

palindrome

Function

Reverse all non-zero digits of your score, leaving zeroes in place

Example

Your score is 42069. The $4269$ flips to $9624$, so your score becomes $96024$.

quadratic formula

Function

If your score contains a square digit, double your score; otherwise, halve your score

Rulings

The square digits are $0$, $1$, $4$, $9$.

Example

Your score is $4592$. $4$ and $9$ are square, so your score is doubled to $9184$.

rotation by i

Function (stand up)

You have been rotated into the complex plane – you are unaffected by other players’ effects until another player is rotated into the complex plane

Rulings

Other players can still choose to use Items on you, but they will have no effect.

catastrophic cancellation

Function

Choose another player, and calculate the difference between your scores. The player with the lower score has their score changed to that difference

Example

Your score is $1000$. You pick a player with a score of $9000$. The difference is $9000 - 1000 = 8000$, and your score is lower, so your score becomes $8000$.

degenerate case

Function (stand up)

Pick a player; choose 1 of their cells to cross out, without applying its effect.

Rulings

• You can’t pick a cell that’s already been crossed out.
• When that cell is called out in future, that player doesn’t obtain the Item.

inverse function

Action

Cancel out another player’s Function or Action applied to you

Rulings

• Activate this is response to a Function or Action.
• The Function or Action must either affect you, or have been activated in response to your Function or Action.

reflection in y axis

Action

Reflect a Function or Action back at the activator

Rulings

• Activate this in response to a Function or Action.
• The Function or Action must either affect you, or have been activated in response to your Function or Action.
• The effect of the Function or Action is applied to the activator by the reflector.

Examples

• Another player with a score of $1100$ activates [sec] to try remove the last digit of your score. You activate this Function to reflect it back at them. The effect of [sec] is applied to them instead of you, so their score becomes $110$.
• Another player activates [sin] to try steal your points. You activate this Function to reflect it back at them. The effect of [sin] is now applied by you instead of them, so you steal their points.

reflection in x axis

Action

Deflect a Function or Action to another player (other than the activator)

Rulings

• Activate this in response to a Function or Action.
• The Function or Action must either affect you, or have been activated in response to your Function or Action.

negative multiplication

Action

When a player steals your points, they lose your points instead of gaining them

Example

Your score is $1000$. Another player with a score of $4000$ tries to steal your points. You activate this Action, so instead of gaining $1000$ points, they lose $1000$ points. Your score becomes $0$, and theirs $4000 - 1000 = 3000$.

matrix inversion

Function

complex conjugation

Function

Rotate yourself into the complex plane for this turn

Rulings

• If a player is already in the complex plane, they are removed and are not restored at the end of the turn.
