Fifteen calm block puzzle games in one app. No pressure. Just blocks. KaBlok brings together short, relaxing block puzzles. Every game sits one tap from the home screen and introduces itself in three lines the first time you open it. After that there is nothing to read: you just play. FIFTEEN GAMES, ONE APP ⢠BLAST: drag pieces onto the grid and fill rows and columns. A full line with six blocks of one colour sets off a chain reaction bomb. ⢠NINE: block sudoku on a wooden board. Fill lines, columns and 3x3 boxes. ⢠SHAPES: fill the glowing silhouette without spilling past its outline. ⢠SORT: pour the colours from tube to tube until each one holds a single colour. Undo is always there. ⢠MERGE: drop a block onto one of the same colour and the two become one block of the next colour. ⢠POP: tap groups of blocks of the same colour. The bigger the group, the more it scores. ⢠STACK: drop the block at the right moment and build the tower as high as it goes. ⢠TRIO: send tiles to the tray, and three of a kind disappear. ⢠ARROWS: tap a block and it slides out the way its arrow points. Mind the other blocks. ⢠GEMS: swap gems to line up three or more, in 30 moves. ⢠SCREW: unscrew each screw and drop it in the tray of its colour. ⢠BOUNCE: break the blocks with the ball before the wall reaches the line. ⢠CROWNS: one crown per row, per column and per colour, and no two crowns touching. ⢠PIXEL: shooters circle the picture and hit the blocks of their colour. ⢠HEXA: place stacks of hexagons. Top tiles of the same colour slide together, and ten of a colour clear. ONE CHALLENGE A DAY Every game has a daily challenge, the same for everyone, and keeps your personal best. If you like, you can appear on the online leaderboard under a name the app makes up for you, and leave it whenever you want. MADE TO UNWIND Nothing to prove except to yourself. Two minutes on the bus or an hour on the sofa: your call. IN YOUR LANGUAGE Fifteen languages, and you pick yours in Settings. KaBlok is free.

Verdict
The clearest difference is update cadence: KaBlok at weekly against Arf Blocks's fortnightly. KaBlok also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
