Colmo
Read full descriptionHide full description
Colmo is a number puzzle with one rule: every jar has a capacity, and you pour the doses dealt to you until it is EXACTLY full. A full jar bursts and is shelved; a dose that would overflow is refused. Not one short, not one over. FILL IT TO THE BRIM A jar with 7 left bursts when you pour a 7. Pour an 8 and the jar refuses, showing you exactly how far over you were. The whole game rests on that small decision: which dose into which jar? JARS HAVE TEMPERAMENTS Starred jars are the level's goal. Narrow necks won't let a big dose through the mouth. Wax-sealed jars stay shut until a neighbour bursts. Every new temperament is taught by a wordless level. READ NOTHING, PLAY NOW Colmo has no tutorial text. Events teach the rules: your first tap bursts your first jar, your first refusal is your first lesson. Numbers speak every language. 120 LEVELS + ENDLESS Climb the shelf wall bottom to top: level after level, three stars each, and an unnumbered jar waiting at the ceiling. Clear every level on a shelf and the whole chapter pays out. THREE JOKERS Hold sets a dose aside for later. Undo takes back your last pour, budget and all. Swap trades the dose you were dealt for a new one. Each level hands you the jokers it expects you to need, and coins you have earned can buy one more. NO CLOCK ON THE BOARD No level is timed and nothing rushes your turn. Think it through on the bus, on a plane, in a queue: Colmo plays offline, and your progress is saved on the device. Signing in is optional and only adds a cloud backup. FEATURES - Finish with doses to spare for more stars - Optional sign-in for cloud save (never required) - Short sessions, playable one-handed - A logic puzzle with nothing to read Like sudoku in one way only: nothing to read. The rule is different, fill each jar exactly. Download it and fill your first jar. The jars explain the rest.

Verdict
The clearest difference is in-app purchases: Refract at none against Colmo's 1. Refract also leads on ads (none vs shown). Colmo's advantage is update cadence (every 2 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
