Puralax vs Number Pyramid

Puralax is a simple puzzle game where you need to paint every colored tile into one single color to complete each level. Each level has a different target color, indicated by the color of the top bar on the screen. Rules are simple: You can move colored tiles between white empty cells in vertical or horizontal directions (one cell at a time), or you can paint a neighbor tile by dragging one tile into another. Each tile has a limited amount of moves, shown by little white dots inside it. When you paint one tile, you can generate a chain reaction that will begin to paint every attached tile from the same color. The first six levels comes with an assistant that remind you the rules and tells you which tiles move where. So, what are you waiting for? Start painting, and remember... colors are alive!

Just addition. And yet your whole mind is working. Number Pyramid is a simple training app: add the numbers next to each other, row by row, until you reach the single number at the top. The only arithmetic is single-digit addition. Somehow it is still hard. WHAT YOU ARE TRAINING IS MEMORY, NOT ARITHMETIC Working memory is what holds something in mind while you do something else with it. 3 5 6 1 4 Starting from that bottom row, you work out 8, 11, 7 and 5 — and then you have to keep all four in your head while you start on the row above. Hold, calculate, hold again. That loop is what this app makes you repeat. No paper, no pen. Build the pyramid in your head. THREE STEPS 1. Look at the numbers along the bottom 2. Add each neighbouring pair and climb, row by row 3. Type the number at the top and tap Answer The pyramid then opens one row at a time, so you can see exactly where you slipped. EIGHT LEVELS, FROM 3 ROWS TO 10 Three rows takes a few seconds. Ten rows and the number of things you have to hold at once jumps. You cannot start at the top: three correct answers on a level unlocks the next one, so you climb a little above your current limit instead of drowning.
