Cross Math Z — The Ultimate Math Puzzle Challenge

Think you know your numbers? Cross Math Z puts your arithmetic skills to the ultimate test in a fresh, addictive puzzle experience unlike anything else on mobile. Place tiles, solve equations, and climb through 750 levels of pure mathematical challenge.

Place numbered tiles on a cross-shaped grid to complete equations both horizontally and vertically at the same time. Every placement counts — one wrong equation, three strikes, and you lose a life. Run out of lives and it is game over. Do you have what it takes to reach the top?

CROSS PUZZLE MECHANICS
The gameplay is simple to learn but endlessly deep. A grid of cells awaits, some locked with fixed operators and numbers. Your mission: place the right tiles to satisfy every equation across every row and column simultaneously. As you advance, grids grow larger, numbers grow trickier, and the time pressure intensifies.

SIX UNIQUE GAME MODES

Classic — Progress through 750 hand-crafted levels, each generated from a fixed seed for a consistent yet ever-evolving challenge. Grids scale from 2 waves per level early on to 5 waves at the highest tiers, with a countdown timer that appears at level 10 and tightens all the way to level 750.

Zen — No timer, no strikes, no pressure whatsoever. Pure puzzle solving at your own comfortable pace. The ideal mode for those moments when you want to think without any stress.

Rush — A relentless wave-based sprint. Every puzzle you solve tightens the clock for the next one. How many rounds can you clear before the timer finally catches up to you?

Blitz — Sixty seconds, unlimited puzzles. Solve as many as you can in one frantic minute and post your best score to compete with others.

Survival — Every wrong equation drains precious seconds from the clock. Stay sharp and keep your equations clean, or face an early end.

Daily Challenge — A brand-new puzzle generated fresh every day, identical for all players worldwide. Solve it to earn special rewards and maintain your daily login streak.

DEPTH AND STRATEGY
The further you progress, the richer the mechanics become. Locked cells block your path until adjacent equations are completed. Fusion tiles hide a large number split into two halves — place both in the correct positions to unlock the cell. Lightning-fast placements earn speed bonuses. Three undo charges per level let you correct costly mistakes before they spiral out of control.

POWER-UPS AND REWARDS
Earn gems by completing levels with stars. Spend them in the shop on bonus charges. Use Time to add extra seconds, Reveal to expose a hidden number, Eliminate to remove wrong candidates from a cell, or Freeze to pause the countdown entirely while you think. Rare bonus drops fall randomly after level completions, giving you an edge when you need it most.

ACHIEVEMENTS AND CLOUD SAVE
Dozens of achievements cover every facet of your mastery — from your very first cleared level to elite challenges such as finishing levels without any undos, surviving on a razor-thin clock, or maintaining a 30-day daily streak. All progress is automatically synced via Google Play cloud save so your game is never lost, even when switching devices.

FAIR BY DESIGN
No pay-to-win. No energy system that forces you to stop playing. Lives recharge automatically every 20 minutes, and every game mode is available from the very first session. Cross Math Z is built for players who want a genuine mental challenge that rewards skill, consistency, and persistence above all else.
