[TRY BEFORE YOU BUY!] A beloved PC game, now coming to mobile. Metacritic: 83. Very Positive on STEAM - 90%. Drop Duchy takes the iconic geometric puzzle gameplay we all know and love and gives it a fresh perspective: instead of simply clearing lines, you build a realm. A mix of deckbuilding, puzzle and rogue-lite, designed to hone your appetite as a block-stacking tactician. Place tile pieces as you would in a block-dropping game, but align them to maximize their activation rules. Set the right structures next to lush forests, wild rivers and grassy plains to pull out maximum resources and units. Then gather your troops, reclaim the regions under enemy control, and storm the enemy fortress along branching, decision-filled paths. Let your castle take too much damage and the run ends - but defeat is not the end: jump straight back in with a new strategy, and use the experience gained to unlock even more content. Grow in power with over 110 unique cards, trade with markets and guilds, and climb a meta progression of over 90 missions tied to three playable factions: The Duchy, The Order and The Republic. Adapt, conquer, and keep the action moving!

Sum Fall
Read full descriptionHide full description
Sum Fall is the arithmetic puzzle game that plays by its own rules. Place numbered pieces on the grid. Watch them fall — up or down, you never know which way. When two pieces meet and their values add up to 0 or 10, they vanish. Clear them all before the grid overflows. Simple to learn. Fiendishly hard to master. HOW IT WORKS → Each turn, choose where to place a piece in the center row → Pieces fall toward the ceiling or floor — direction is a mystery → Adjacent pieces fuse: green (+) adds, red (−) subtracts → Result is 0 or 10? Both pieces vanish and you score → Chain vanishes for multiplier bonuses: ×1.5 → ×2 → ×3 → ×5 NEW — DAILY CHALLENGE One handcrafted puzzle a day — the same for every player. Clear the board, race the clock, earn up to 3 stars. Keep your streak alive, replay past days from the calendar, and complete a full month to earn a trophy. NEW — DEMOLITION An endless series of solvable puzzle levels. Destroy every golden cell with a limited piece budget. Bombs, armored cells, mystery values, cyclic counters… plan your chains, finish under par, claim all 3 stars. THREE ENDLESS MODES EASY — No pressure. Practice at your own pace. CLASSIC — From turn 10, a new row pushes in. Stay ahead of it. HARDCORE — Both sides push simultaneously. Every move counts.
