BUILD. LOCK. KNOCK.
This is total war.

Build stacks of matching numbers. Seven cards locks a stack forever — locked stacks can't be touched. Knock cards off your opponent's unfinished stacks before they lock. Locking 2 stacks ends the game — points win it.

Your arsenal.

NUMBERS 1–10

Start a stack with any single number, then add that same number to it. Seven cards locks the stack — locked stacks can never be knocked. All numbers = a clean stack, the most valuable kind. Every number is also a weapon: play it at your opponent's matching stack to knock its top card off. There are 18 of every number in the deck.

WILD BOMB

The deck's only special card — 36 of them, and every one is a hot potato. Build it into your own stacks as a wild (any mix of numbers and Wild Bombs is allowed), or throw it to knock any unfinished enemy stack — no matching required. One on top of the discard pile turns the pile true wild. But hold one when the game ends and it costs you a point. Spend them, or shed them.

Designed to be read.

A card you can't read isn't a card — it's a guess. We researched what actually helps people who have a hard time seeing — published vision science on aging eyes and low-vision reading guidelines — and rebuilt every number card around it, so everyone can play with total confidence:

Big, bold numerals — no glow. The number is the biggest thing on the card, in crisp bold type. We removed glow effects entirely: research on halation shows glowing text blurs edges — hardest on the roughly one in three adults with astigmatism.
Bright faces, dark ink — like real cards on felt. Peer-reviewed legibility research (Piepenbrock et al., Ergonomics) found dark characters on a light background read better at every age — a bright card face sharpens the eye's focus, which matters most for older eyes.
Contrast we measured, not guessed. Every numeral tests between 8:1 and 12.9:1 against its card face using the WCAG formula — beyond the strictest AAA standard (7:1), which is calibrated for roughly 20/80 vision.
Colors chosen for aging eyes and color-blindness. The aging lens yellows and swallows blues — blue-vs-purple is the most documented color confusion in adults over 60 — so our ten card colors keep those apart, follow the colorblind-safe Okabe-Ito palette principles, and never rely on color alone: the numeral always carries the value. The 6 and 9 are underlined so they can never be mistaken for each other.

And we're not done: braille physical decks and a fully-voiced audio mode — the whole game announced play-by-play, for players who are blind — are on our roadmap.
