• ✓A painted playroom behind it — a game about a shelf belongs in a room that has one
• ✓The mid-round result is a ✓ banner with a countdown, then it moves on by itself — no press
• ✓A level icon in the HUD, so you can change level from inside a round
• ✓The finish card goes through GameShell's overlay, so it is always centred — as a child of the stage it slid off the bottom-left
• ✓Idea: this does not train the eyes, it trains a method of searching
• ✓The technique is said out loud: one shelf at a time, left to right — never dart about
• ✓The difficulty dial is whether the shelf was REORDERED, not how many things are on it
• ✓Reordered, position tells you nothing — you must compare as sets, a real jump
• ✓A second mode: which has no pair — where the method is pair-off-and-discard
• ✓Hints narrow the search, never point at it: 3 rings a shelf · 5 dims the others · 8 breathes
• ✓Every picture is one of the 145 existing Kidsquare paintings
• ✓Pools are grouped so one shelf reads as one place, never a lion beside a kettle
• ✓The washing-line mode: socks on a line, which needs a painted sock setplanned
• ✓The box mode: match each pile to the box it came out ofplanned
• ✓The give-it-back mode: each child's own backpack and hatplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
