Paper War

Two armies folded from paper push and pull the front line like a tug of war. Tap the roulette and soldiers fold out and march down the road; tap again while it spins and it turns into a row of reels, where matching soldiers in a line get stronger. Pick which of the two lanes to send soldiers down to block or break through, and capture the outpost in the middle of the road. Wreck the enemy camp first to win. Fill the star gauge to advance an era and your soldiers and castle change from newspaper to colored paper, cardboard and the sky above the clouds. After stage 120 the extreme Endless Challenge begins.

• Roulette tickets pile up beside the roulette over time (up to 5). Each tap on the roulette in the lower part of the screen spends one ticket.
• Tap again while it spins and the roulette turns into a row of sideways reels — each tap adds one (up to 5). 2 seconds after your last tap the reels stop, and the soldier in the middle slot of each reel folds out and marches down the road.
• When the same soldier lines up across, down or diagonally three or more times in the reels' top, middle and bottom slots, you complete a line! Grades go up or extra soldiers come out. Grades show as colors (white · green · blue · purple · gold).
• Soldiers march along two lanes. Tap a flag at the end of a lane to pick the lane your soldiers go down (tap the same flag again to alternate). Soldiers only fight enemies in their own lane; a soldier in a lane with no enemy keeps walking and hits the camp (a Commander blocks both lanes).
• Spend tickets on upgrades that last only for this stage: Luck (higher grades come up more — 5 tickets each, as many times as you like) and Favorite (the slot you pick gets wider on the roulette — 1 · 2 · 3 tickets, up to 3 levels). For Favorite, tap the pin button then a slot, or long-press a slot.
• Soldiers follow Shield > Charge > Ranged > Shield. ▲ shows an advantage, ▼ a disadvantage. Tap the book button at the top right to open a codex of every soldier's abilities and matchups.
• From stage 4, an outpost sits in the middle of the road. When only one side's soldiers stay in it for 3 seconds, that side captures it and its soldiers march out from there (an outpost on your side also makes tickets pile up 10% faster).
• Wreck the enemy camp (3 blocks) first to win. A stage starts at 125 seconds and later ones run longer. In the last 10 seconds camps take double damage; when time runs out, Overtime begins, the multiplier climbs to triple, quadruple … every 10 seconds and both camps burn down.
• When the star gauge is full, tap the cap in the roulette's center to advance an era.
• Each stage brings twists like Commanders, fog, gusts and lightning. From stage 121 the extreme Endless Challenge begins.
• ★1 for winning, ★2 for keeping all your camp blocks, ★3 for a fast win (on Commander stages, defeat the Commander).
