Digit Defense

Every digit is a gamble. Digit Defense is a luck-based tower defense where every character is a number.

Monsters march in a loop around your board. Summon digits, merge them, and stop the mob count from reaching the limit. An AI partner defends the second board and shares your mob gauge, so every wave is a team effort. The game is single player and needs no account.

◆ SUMMONING IS PURE LUCK
Every summon is random, from Common 1s to Legendary 144s. Forge your summon level to bend the odds in your favour.

◆ MERGE THREE OF A KIND
Stack three identical digits in one cell and merge them into a random digit of the next rarity. You never quite know what you will get.

◆ SPIN THE ROULETTE
Sell spare digits for luck stones, then take a swing at the Rare, Epic and Legendary wheels. Misses build pity on the lower wheels.

◆ SOLVE MYTHIC EQUATIONS
Mythics are solved, not found. Every recipe is true arithmetic: 42 = 64 − 16 − 6, 1024 = 64 × 16, 1729 = 144 × 12 + 1. Collect the numbers on your board and solve the equation to create Pi, Euler, Jackpot, Not Found, Taxicab and more. Immortals go further still.

◆ REAL BOARD DEPTH
• Even digits deal physical damage, odd digits deal magic, and parity bosses punish a one-sided board.
• Melee digits must stand on the outer ring. Ranged digits can hold the centre.
• Mana skills, stuns, slows, defence shred, crits and auras all stack up.
• Enhance mythics mid-match, safely with stones or gambling with coins.

◆ BOSSES, CHALLENGES AND MISSIONS
A boss every ten waves must die before its timer ends: Sprinter, Jammer, Parity, Mitosis, Silencer, Regrowth and Overflow. Start optional challenge bosses for stones, and clear 20 field missions in every match.

◆ MODES AND COLLECTION
Climb Normal, Hard and Hell, chase your record in Endless, and take on the Vault for prime shards and modules. Level digit cards, unlock and upgrade mythics, research the Lab, climb 54 divisions and ascend for permanent power.

Test your luck. Solve the numbers. Hold the board.
