Zerko vs Mapzzle

Some call it reverse sudoku, while others call it a nullification game, but it's Zerko - a puzzle game filled with shapes, numbers, and a straightforward goal: make every number zero. To achieve this, you need to strategically place blocks of various shapes and values so that the numbers on the board effectively "remove up" to zero. Like all my games, this one too is about relaxation... Just chill. There are no points, no time pressure, no data collection, no in-app purchases, no ads, no nonsense ;) My only hope is that you'll enjoy it and that I'll be able to add new content and levels for you in the future.

Put the world back together. Mapzzle turns 600 real maps into geography puzzles. Build each one as a jigsaw, or play it as a map quiz and see how many places you can find. The Starter Pack is free, so you can jump straight in. In Jigsaw mode the map starts out in pieces. A piece clicks in when it touches the outer border or a neighbor you've already placed, so the map grows from the outside in like a real jigsaw, right up to the last piece. Quiz mode takes all the names off the map, so it comes down to how well you know your geography. The game asks for a place and you press and hold where you think it is. A direct hit gets full points and the biggest fireworks, but a near miss still counts. If that sounds too relaxed, turn on Time Attack and you'll have 10 seconds per question. Some maps take a couple of minutes and others will keep you busy for days. Warm up with the continents or the countries of Europe, then take on Japan's 47 prefectures, every state in Brazil or all 2,477 municipalities of Mexico. Before long you'll point to Mato Grosso without a second thought. Three difficulty levels change how close is close enough, whether you're placing a piece or answering a question. A quiz can be 5, 10 or 20 questions long or cover the whole map. Each map keeps your best time, best score and stars, so there's always a record to beat. There are 62 achievements to collect too. Mapzzle also takes care of the little things. • Maps you've downloaded play offline • Close the app mid-game and pick up right where you stopped • If you get stuck, open the guide map or ask for a hint that shows where a piece goes • 9 visual themes with their own color palettes • Play in 16 languages Your six free maps include the US states, London's boroughs and the Caribbean islands.
