Operation Blast

Two gates. Two seconds. +7 or ×2?

Pick right and your blaster roars. Pick wrong and the horde gets closer. Operation Blast is the math-gate runner you keep seeing in ads, except here it is the whole game: 100 levels, a fresh Daily Run every day, a horde to hold off, and no ads.

EVERY GATE IS A CHOICE You run. Two signs come at you. Add, multiply, halve or take away, and the number over your head changes the instant you pass through. No previews, no hints. At 12, ×2 beats +7. At 6, it loses. You have two or three seconds to know which.

THE NUMBER IS YOUR BLASTER More ammo, more fire. The zombies ahead are priced to the gate you just passed, so the right lane clears the road and the wrong one lets them reach you. Three wrong signs and the horde outgrows your ammo.

ONE THUMB, FOUR MOVES Swipe to change lanes. Up to jump the logs. Down to slide under the beams. Down again in mid-air to drop early. Obstacles cost hearts, and you start with three.

THE DAILY RUN One track a day, the same gates for everyone on the planet, and it only gets faster. See where you land on the daily, weekly and all-time leaderboards. Come back tomorrow and do it again.

HOLD THE LINE Now the horde comes to you. Your hero stands at the line and never stops firing, and the number over your head is rounds per second. Read the sign, shoot the boosts open as they come, and hold through bosses and rush waves for as long as you can. Train each hero, bring their special (OVERDRIVE, SLOW TIME, ROCKET BARRAGE, FOUR BARRELS or FORCE WALL) and climb Hold the Line's own leaderboards.

STREAKS THAT TALK BACK Five right in a row: SHARP! Ten: BIG BRAIN. Fifteen: GENIUS. Fifty: SUPERCOMPUTER. Nobody gets there on the first try.

100 LEVELS, 10 WORLDS, 5 HEROES Forest, canyon, snow, neon city, jungle, volcano, lab, space station and beyond. Every tenth level ends in a boss fight, and bosses turn up in the Daily Run too: dodge the slams, survive the rage, land the finish. Run as Max, Zoe, Bolt, Zig or the legendary Rev. Earn coins for upgrades, power-ups and hats.

FAST MENTAL MATH, DOZENS OF TIMES A RUN Plus, minus, times and divide with small numbers, at speed. That is the entire trick, and every level is a little faster than the last. Good for a two-minute break. Dangerous for "just one more".

NO ADS. NO SUBSCRIPTION. Replay any level you have cleared as often as you like. Four new levels, one Daily Run and one Hold the Line stand are free every day. One Unlimited Pass lifts all three limits for good. Coin packs and Second Chances are optional: heroes, upgrades and hats can all be earned by playing.

Side effects may include doing arithmetic in your head at parties.
